[Request] Unlocked Asus Maximus VIII Hero BIOS 3802

Wondering if someone can help me, I am after a Modified BIOS for ASUS MAXIMUS VIII HERO (not Alpha) Version 3802 that unlocks PCH-F Configuration to give the ability to enabled Intel PTT. If the BIOS also unlocks other featues that would also be a bonus but mainly after this!

I have attempted to use GRUB to edit the BIOS Settings with Secure Boot disabled but this does not seem to work. I have also updated my Intel Management Engine Firmware to 11.8.96.4657 to see if this would also help but it did not, not sure if this needs updating within the BIOS Image itself for compatibility?

Thanks in advance.
