You can use CloudLinux Selector to enable or disable available PHP extensions in Plesk.

 

1. Log in to your Plesk account.

2. In the right-hand sidebar, click on PHP Selector.

 

3. Click on the Extensions menu.

Note: If the Extensions page shows an error related to the native PHP version, change it to a non-native version first.

 

4. For enabling the extension, you will need to tick mark that option. If you wish to disable it, then unmark it, and it will be disabled.
