There is currently no GPO to block this.
You can catch this with a 'health check' script, in particular to
(a) make sure the backup key is backed up (you can set a GPO to require that
this key is always backed up, which will block encryption if the AD is not
(b) make sure the volume is encrypted, and to begin encrypting if the user
manually decrypted it / paused it.
Or, our more preferred approach, is to not allow the user to be able to log
on as an Administrator
