You can log out, then CTRL + ALT + F1 , log in and run the update command. If there was no kernel update, you don’t have to reboot. If some service got updated restart the service (if that was not done by the updater.) Then you can switch back to the graphical session usually by CTRL + ALT + F7) and log in again.
Problem with this is that it’s really hard to figure out whether some update to some minor library is going to affect an application. Sometimes you don’t even know which applications are using that library.
