OK, I understand the risks and I will definitely create a BIOS backup before proceeding with any modifications.

However, I'm not entirely sure how to proceed with the backup process. Is there perhaps a guide on how to do this without external software? And most importantly, something that's compatible with my specific laptop model?

I want to make sure I do this correctly to avoid any complications with the ThinkPad T14 Gen 1 (20S1S4E600).

Like, I know ok, I do the backup but later what? Idk how to put the new image in the bios with no brick frv my laptop...
