Configure Secure Boot

Secure Boot will be configured with owner keys and a password will be set to the BIOS to prevent its deactivation.

Steps

Turn on the server and enter the BIOS (usually with the F2 key).
Configure Secure Boot in "Setup" mode, save and reboot.
After logging in with admin, run: sudo ./scripts/secureboot.sh.
If there were no errors, then run reboot to reboot and enter the BIOS again.
Exit "Setup" mode and enable Secure Boot.
Set a password to the BIOS, save and reboot.
After logging in with admin, run: sbctl status. The message should say that it is installed and Secure Boot is enabled.
