Y540-17IRH Advanced TAB BIOS

Computer Lenovo Y540-IRH w/ i7-9750h and 2060

I have absolutely NO IDEA what to do. Advanced Tab is hidden but I know its there because I’ve stumbled upon it before. Have very very limited experience with assembly language and even less with BIOS modding.

Correct me if Im wrong. While it possible to unlock this BIOS via SPI programmer by dumping and then reflashing, I can also unlock by execrating necessary dump from Insyde BIOS installer and mod, then repackage with setup exe???
Unsure where to go from here.
