It’s a good practice to set your calculations to manual at the beginning of macros and restore calculations at the end of macros. If you need to recalculate the workbook you can manually tell Excel to calculate. Turn Off Automatic Calculations. You can turn off automatic calculation with a macro by setting it to xlmanual. If you have turned off Excel automatic calculation, i.e. Selected the Manual calculation setting, you can force Excel to recalculate by using one of the following methods. To manually recalculate all open worksheets and update all open chart sheets, go to the Formulas tab Calculation group, and click the Calculate Now button.

Then, in the Calculation section of the Formulas tab, click the “Calculation Options” button and select “Manual” from the drop-down menu. Once you’ve turned on manual calculation, you can click “Calculate Sheet” in the Calculation section of the Formulas tab, or press Shift+F9.

In really large Excel 2016 workbooks that contain many completed worksheets, you may want to switch to manual recalculation so that you can control when the formulas in the worksheet are calculated. You need this kind of control when you find that Excel’s recalculation of formulas each time you enter or change information in cells has considerably slowed the program’s response time to a crawl.
By holding off recalculations until you are ready to save or print the workbook, you find that you can work with Excel’s worksheets without interminable delays.
To put the workbook into manual recalculation mode, you select the Manual option on the Calculation Options’ button on the Formulas tab of the Ribbon (Alt+MXM). After switching to manual recalculation, Excel displays CALCULATE on the status bar whenever you make a change to the worksheet that somehow affects the current values of its formulas. Whenever Excel is in Calculate mode, you need to bring the formulas up-to-date in your worksheets before saving the workbook (as you would do before you print its worksheets).
To recalculate the formulas in a workbook when calculation is manual, press F9 or Ctrl+= (equal sign) or select the Calculate Now button (the one with a picture of a calculator in the upper-right corner of the Calculation group) on the Formulas tab (Alt+MB).
Excel then recalculates the formulas in all the worksheets of your workbook. If you made changes to only the current worksheet and you don’t want to wait around for Excel to recalculate every other worksheet in the workbook, you can restrict the recalculation to the current worksheet. Press Shift+F9 or click the Calculate Sheet button (the one with picture of a calculator under the worksheet in the lower-right corner of the Calculation group) on the Formulas tab (Alt+MJ).
If your worksheet contains data tables that perform different what-if scenarios, you can have Excel automatically recalculate all parts of the worksheet except for those data tables by clicking Automatic Except Data Tables on the Calculation Options button’s drop-down menu on the Formulas tab (Alt+MXE).
To return a workbook to fully automatic recalculation mode, click the Automatic option on the Calculation Options button’s drop-down menu on the Formulas tab (Alt+MXA).

In excel I have a worksheet with over 30,000 rows. Sample data is shown in the image below. About a dozen of the columns have formulas which really slow down the work whenever I update a cell. I would like to use VBA code to turn off automatic formula calculation for only 5 columns (see columns in red in example). The formulas in the columns in yellow would run all the time. I would then like to create a macro that calculates the formula in the red columns whenever pressed.
I tried looking for some options in the formula ribbon but wasn't successful.

If you are creating a macro
But if you just want to enable and disable.. Go to the menu (from the ribbon) Formulas / Calculation Options and select Automatic or Manual as desired.

Instead of turning off calculation for a few columns, better to use a macro that calculates your resource-intensive formula and then saves the result as a value. You can even get it to only process blank cells or #N/A cells in the event that you only need to process things that didn't previously return a result. Just today I did the same for a computationally expensive FuzzyMatch routine I've written.
However, if your formulas are doing something such as crunching data via SUMPRODUCT or doing lookups on very large arrays, chances are you can optimize them so that they run in a fraction of the time, and thus completely avoid the need to selectively recalculate your sheet. And if those formulas are Volatile - or downstream of volatile functions - then chances are you can use non volatile formulas that stop your spreadsheet recalculating at the drop of a hat.
For faster SUMPRODUCT alternatives, see my answer at Optimizing Excel formulas - SUMPRODUCT vs SUMIFS/COUNTIFS
For much faster lookups, see my blog post at http://dailydoseofexcel.com/archives/2015/04/23/how-much-faster-is-the-double-vlookup-trick/

For more on volatility - including how to avoid it - see my blog post at https://chandoo.org/wp/2014/03/03/handle-volatile-functions-like-they-are-dynamite/
For more suggestions, edit your post to include information on the formulas you are using, including how many formulas, what size ranges they reference, and what you're trying to achieve with them.
