Help with Acer Bios Variables

[BKJ2]

I am new to BIOS modding so please bear with me. I have used Andys tool to dump my bios. I have also used Module Helper and Universal IFR Extractor. From what I see, I need to change variable 0x12 and 0x11 to add the advanced menu to my BIOS. I don't know how to change the variable with a hex-editor. I have looked and could not figure it out. So I used bootx64.efi. After booting I changed the values of 0x12 and 0x11 and it did not add anything to the BIOS menu. I have everything saved and can provide whatever information is requested to help me out on this. Thanks in advance for all your help.
