[REQUEST] Clevo P751ZM (mobo P750ZM-G) BIOS unlock

Hello and happy new year \o/
I have a laptop called Berserk MK1 from Materiel.net but in fact its a Clevo P751ZM (the current motherboard is P750ZM-G).

I love this laptop who's a gift from my parents for my degre (2016).

I research a full unlocked and upgraded BIOS, if possible compatible with my GTX 1070 MXM (upgrade from 970M).
My GTX 1070 is a Clock/memory/boost 1518/2002/1733 vBIOS 86.04.72.00.12 (Subvendor Clevo/Kapok).
A few Mhz are not refused 

I had issues with Intel and Samsung SSD's for raid 1 break i think due to the "ME FW" 

If it's possible to unlock g-sync, i've read if the GPU isn't based in g-sync it can't (my original 970M was g-sync)

The BIOS of my Clevo is the lastest:

  Mobo-E0309.zip (Size: 56.4 KB / Downloads: 1)

The original vBIOS of my GTX1070 is this one (Internal display and HDMI work, no g-synch):

  GPU-stock-GP104-86.04.42.00.03.rom.zip (Size: 148.68 KB / Downloads: 0)

I've flash the vBIOS with this version (Internal display, two display port and HDMI work, no g-synch):

  GPU-updated-clevo-GTX-1070-8-GB-BIOS-207530.zip (Size: 151.22 KB / Downloads: 0)

I want a unlocked BIOS to undervolt my delid (Artic Silver MX-4) 4790K, XTU don't work.

I gonna upgrade the delid with cooper and metal liquid and maybe metal liquid on the GTX1070. 

In the BIOS:
The ME FW Version: 0.0.0.0 sometimes it show 9.1.20.1035
BIOS version 1.03.04
KBC/EC Firmware Revision 1.03.09
VGA Card: Unknown
vBIOS Revision: 86.04.72.00.12
vBIOS Build Date: 06/14/17

I'm able to flash the BIOS for example with the CH341-Programmer (i've bricked the GTX1070 previously )

Big thanks in advance
