Hello Guys,
currently i am trying to get a hackintosh setup on this notebook and i would like the BIOS to do the following:
Disable the nVidia Graphics card and only use Intels internal one, but i also need to set the memory size of the intel graphics card and maybe some other options, so having the advanced menu visible to change everything would be even better.
Remove WLAN Module Whitelisting, so i can change the Module.

What i have seen so far, i could use the EFI Shell to disable the graphics card if i know the correct offset.
For this i downloaded the files above, extracted them with 7-Zip and was provided with Files that were quite an odd size.
I then executed the "InsydeFlasher.exe" and choose to copy the files elsewhere, which then ended up in the files being exactly 8192KB in size and a valid BIOS File in Phoenix Tools.
I opened it up in Phoenix Tools to get the Dump Folder, found the file called:
FE3542FE-C1D3-4EF8-657C-8048606FF670_1465.ROM


But "uefidump.pl" as a perl script only gave me an error and could not find packages inside the file.
I now believe that maybe the file is encrypted, but then it should not have been possible for Phoenix Tools to open it, right?

I then tried the older BIOS, also linked above, and flashed it via Recovery Mode to get an Downgrade.
The BIOS sadly still looks the same, since i hoped the advanced options were maybe available in the older BIOS.

It would be awesome if someone else could help me out here and tell me which tools to use, because i would like to learn from it and not only get the log out put with the specific value, Thank you.

UPDATE ----------------------------------------------------------------------------------------------------------------------

I now extracted the IFR from the ROM with the "Universal-IFR-Extractor", attached below.
But i am still not able to find the correct variables to change the graphics unit.

UPDATE 2----------------------------------------------------------------------------------------------------------------------
I finally found something!

Code:

Now i am searching for a way to disable the dedicated graphics card, maybe only switching the primary option to internal will do the trick, i will tryit out and report back.

UPDATE 3----------------------------------------------------------------------------------------------------------------------

I am stuck at changing/setting the variable in the EFI Shell.
My USB Stick boots fine into UEFI with the headline "grub 2.0" but as soon as i set the variable:
setup_var 0x186 0x0
It shows me the correct default value for that variable (0x4), but then it shows the following error:
"setting offset 0x186 to 0x00
error: can't set variable using efi (error: 0x000000000000001a)"

UPDATE 4----------------------------------------------------------------------------------------------------------------------

Using the UEFI Interactive Shell which also comes with Clover i am able to permanently write data to the variable, which is great!
I extracted the GUID and name by using lubuntu 16.10 and printed them using "efivar -l" and found the "SwitchableGraphicsVariable".

My Hackintosh Setup still does not boot, but i now have found a way to get what i want.
Even if i was talking to myself the whole time, thank you very much and hopefully this thread will also help someone else.
