[Request] Dell Inspiron 7586 2-in-1 bypass security check

Hi Experts,

I tried to flash modded BIOS to my Dell Inspiron 7586 2-in-1 with a CH341A programmer to unlock advanced bios menu.

However, any modification to the BIOS region will make my laptop not POST. It seems that Dell has a built-in security check to
prevent users from using modded BIOS, which I don’t know how to bypass it.
Could any experts on this forum teach me how to bypass this security check?


Here is my BIOS file with Flash Descriptor modified.

Thank you.
