Hello
Is it possible to change this setting for specific Users?
For example only for Users in a specific AD Group?
Best Regards

Hi Kevin,
It’s not possible to disable one user profile property for a specific group.
However, you can restrict users/groups from editing their profile by setting the permissions for User Profile service application.
But users will not be able to edit any profile information.
Cheers,
Vathzi
