Regarding dun sa settings, di ba kung shift double click mo yung bear icon may lalabas
Boot Frozen
Boot Thawed for next X Restarts (where X is a number)
Boot Thawed
If you select Boot Thawed (the 3rd option), Deep freeze will be disabled for as many restarts as you like. It will only be activated again when you Shift double click the bear icon and click Boot Frozen then restart.
