If your users have KDE to logon to the system and you want to disable the visual buttons of shutdown and restart for non root users than use the following steps

Go to start menu > control center >system administration > login manager > shutdown

and select allow shutdown local to root only, this will prevent other non root users from messing around and shutting down your system.

Users may also open a terminal and bring the system down from the shutdown command (or many

of its alias like reboot/halt)so you may also need to adjust the execute permissions on these files.
