For my Acer C740, I recall it being really simple.
The instructions were easy to understand and only had a few steps.
I removed a physical write-protect screw, booted to developer mode or something, ran a command in a terminal, and then it either flashed a new BIOS or I booted a Linux USB and flashed a new BIOS.
Either way, it’s a regular computer now.
I can pop in any USB drive and boot whatever EFI-compatible OS I want.
