Changing a hidden option in my bios (Acer Aspire Vn7 592G)


I want to change a variable in my bios but sadly I can’t do it by myself.
The problem now is, that I don’t know how to change the variable in my dumped bios file.

I already know which variable I want to change and it would have been easy to do so if it worked with boot64.efi, but sadly I have to do a hardware mod. I think it is blocked by the vendor to do such changed over boot64.efi.

I just don’t understand how to change the variable in the dump and flash the change to my bios chip. I hope someone can help me with this! Thank you in advance!
