Yes I have LUKS encryption enabled so I think I have to have secure boot enabled. Should I try to disable it?

I did message them and they said the distro may just use and old base that it doesn’t support I guess.

The system 76 open firmware I probably shouldn’t have said custom lol I do the one time boot from USB option in the startup menu. I messaged them and they said it could be because the distro uses an older legacy base.
