@Lost_N_BIOS
Great information, thanks alot!
Just to be sure, those changes to null have to be made only on that same platformdxe module, correct?
Also, should i worry about checksums? Or just change the variables with hexedit and flash it?

Ok, I’m extracting pe32 setup image ‘as is’ with uefitool 21.5, altering bits as you mentioned above in hxd editor according to the generated IFR file… after changing bits to FF and only that, saving file as .bin, and replacing ‘as is’ using same uefitool version… the new bios saves successfully, but when opening new generated file, i can no longer expand main dxe volume… Just like other uefitool versions se tried… Am doing something wrong? Or this is normal? There is no error like “no uefi data” i Just cant expand volume…
Also, I’m modding a full image dumped with programmer, is that alright?

I found a bios of a very similar mobo (dp55wg) that has alot more options on its setup, like you said, seems to be the exact same structure for both bioses, the setup module is exact same place and it is almost identical, the only difference is that some settings, like voltage override for example, have alot more options to it, as opposed to the +50 and +100mv i have on my current BIOS… would i be able to replace my setup module with this one? If i cant do entire module, maybe add values based on the dp55wg setup module values, like add the 1.300v option to my setup using the dp55wg setup module as reference?
Update
I realized today that I can successfully edit the .bio file by method already described above. Since is the .bio file, I tried to flash it with normal .exe. The flash went successfully! But the setting was still gray in BIOS… I only tried to ungray "core ratio limit 4" just to see if I can flash with .exe, maybe I have to edit every setting above to ungray things?
I did not tried to flash the .bin file with programmer since the compressed section do not expand anymore after mod, does this mean the bios is broken?
Update 2
I think I manege to get things going… I dump full image with phoenix tool, edited module to unsupress/ungray settings, nd put it back in, everything with phoenix tool. Now the modded image opens up fine in uefitool, compressed section can be normally expanded and my alterations are there ( checked with ifr extractor)!
Now I have two question, if I extract bios region from that file with uefitool, can I flash it with fpt if s3 state bug work??
Also, @Lost_N_BIOS would you be able to check the modded image pls? I just wanna be sure everything is kinda fine, or if there are any major error that would prevent boot… since is such a pain to take it apart to use programmer!
