Hey, Thanks for reaching out to us.

The ‘Control Apps’ restriction under the user from force stopping the application and clearing the data and cache of the app. In most devices, this also blocks the modification of app permissions.
Please note that this is supported only on Android Enterprise devices.

Kindly use the help link for a reference.

Cheers!
