Oh well, vBIOS edit isn't that hard. I'll ask @lordkag if he could add an option to remove GOP Image to his GOP Updater/Edit tool.

I have one final question about this Dell BIOS. With an OEM ROM the Boot Screen defaults to the PCIe GPU. Problem with that is the iDRAC (IP Remote Access) can only see output from the Integrated GPU. Not having any display until the OS has loaded isn't ideal via IP KVM.

I can set these two options manually in my ROM to fix the issue, but it would be great to un-hide the menu options also.

Internal Graphic Device -> Internal Graphics Device [Auto,Enable,Disable] (Needs to Default to Enable)
Pci Express Graphic -> Always Enable [Enable,Disable] (Needs to Default to Disable)

Both these are hidden options, under hidden menu's. Which I know you said were the hardest kind. I'll just post my modded ROM's if it's too hard.

@theunknown - Yes, an option like that would make it very easy for those that aren't good at hex editing, but they'll still need to figure out how to use GOP Updater tool
Yes, for Insyde BIOS, if it's not easy for me to locate how to unhide the hidden menus, then nothing I can do (unless you want to test a bunch of possibly brick BIOS until we find the correct edit, not ideal for either of us really)
Maybe I can find it though, I will try

Peripheral Configuration >> Video Config >> Internal Graphic Device
Peripheral Configuration >> Pci Express Graphic >> Always Enable

So, you can't see Peripheral Configuration, correct? Show me images of what you can see in BIOS, just one image of each main page
