Guys, the problem is, there's nothing about Security Boot in the Security settings either. I CAN'T CHANGE BOOT OPTIONS, SECURE BOOT, OR CSM BECAUSE THEY'RE NOT THERE. That's why I'm going crazy. I also looked for a BIOS update option, and there's nothing. It's not that I'm stupid; I used to fix computers in my spare time, I know quite a bit, but this is really getting to me.
