[Request] Dell Inspiron 17R SE 7720 bios unlock (or help to do it)

Hi all,

I want to unlock the BIOS of my Dell Inspiron 17R SE 7720, mainly to disable HyperThreading and to manage some advanced BIOS settings.
All online BIOS I found are old and/or link are broken.

I can try to mod it myself if someone can explain what to look in the BIOS file

Here’s the BIOS A17 (EXE and CAP files): https: //easyupload-DOT-io/6azcdf

I am experiencing the same issue but I need to have my dell accept a non OEM battery.
Does anyone in this forum know how to hack BIOSes??
How T F did Linus Tech Tips do it?
