Need help unlocking region me encrypted

i need to unlock region me from this bios and I need to know how the region is unlocked

Every time I try to modify the ME REGION of this (ECS) bios, the bios changes its original weight instead of weighing 8mb, it weighs 2mb, I think it is encrypted or protected.
