Hi, please help me unlock CFG Lock and increase DVMT pre-alloc value to 128MB and unhide Advanced menu! I'm trying to install Hackintosh but some hidden features cause me so many troubles.

Specifications:
Lenovo Thinkpad L390
Intel Core i7-8565u
Intel UHD Graphics
BIOS R10ET50W (1.35 ) on 2021/3/30

I tried to use Intel FPT to dump bios both in DOS and Windows(10 and pe) but failed, and I tried to use Universal BIOS Backup ToolKit 2.0 but failed too.Please instruct me how to dump in other way.

I also attached here the original BIOS exe file for your reference.
