* Checked checkbox, entered my password, rebooted, ended up in UEFI screen
* When opening the checkbox reflects the state of the flag (e.g. checking, closing, opening will keep the checkbox checked so you can unset the flag again)
* Unchecked checkbox, entered my password, flag was unset
* Checkbox is only shown if supported
* Checks for UEFI and shows "UEFI" instead of generic "Firmware" labels, not sure if that stuff actually works when you didn't set up your machine as UEFI boot
I originally considered adding a dropdown to logout screen or some context menu action in the app launcher but since this is quite a niche task to do it's fine to have it in systemsettings somewhere imho.
Checkbox with tooltip
{F6662353}
After typing the password when having checked it
{F6662969}
Suggestions on wording welcome
