Customers can change version of PHP for their hosting account.
You can also manage the modules and features of PHP for your site.
To change the version of PHP - go to the CPanel control panel.
Find the item "Select PHP Version" and there you can select version of PHP and enable / disable the necessary modules.
If you do not have the item "Select PHP Version" in CPanel (or it is not activated)
That means you have another similar module: "MultiPHP Manager"
