At NASA for 25 years!?!, please except my sincere apologies. You guys send G3 iMacs into space to explore Mars and look deep into the universe with stunning JWST images!. I know we have a couple of NASA engineers here, maybe you know
@wstrohm?, his JWST Status thread is awesome!.
Are you downloading the 'Z490 Vision D' EFI from HackinDROM?, I see it's listed and matches your profile. I would download that to a USB's EFI partition and start removing or adding things to see what works and what doesn't. You'll have your working EFI to fall back on.
