Acer aspire v3-372 unlock advanced settings

Hi all, I am new and I want to unlock my latest acer InsydeH2O® UEFI BIOS firmware. I tried any key combination with no success and I think we need to unpack, modify and then repack and flash. I was able to extract and get my fd file which is Mik112.fd . I also converted this file in bin format, after that I stopped doing anything cause I don’t know which part of this file I should modify to unlock the advanced settings.
Please can someone help me out?
Thanks
PS: i can provide the original exe file and the extracted fd file
