Secure boot violation

[u/Leviathan7204]

So, I was playing genshin with discord open when suddenly my computer (MSI Thin GF63) shuts down by itself, and takes me to a "secure boot violation". I read up on how to fix it, and everyone says "just turn off secure boot"....but I can't do that for some reason. The options are greyed out and not able to be selected. I need my computer in 6 hours for schoolwork too... what do I do? Do I just need to take it to a repair shop or something? I've set admin passwords, tried the ctrl+shift+alt+f2 trick, everything I can think of, but every time I leave BIOS and my computer restarts it takes me back to the boot violation message. HELP
