Remove 'Restart' & 'Shutdown' icons from login screen

Hi all,

I’m using version 11.1 with the GNOME desktop and I was wondering if there was a way of removing the ‘Restart’ and ‘Shutdown’ icons from the login screen? Also is it possible to remove the list of users as well?

I’ve tried setting the below to be true in the Gnome Configuration Editor but after a reboot it hasn’t made any difference.


Any help will be much appreciated.
