Dell Inspiron 5680 BIOS Unlock iGPU with dGPU installed.

[r3dlobst3r]

Dell, in their infinite wisdom, disables the Intel iGPU if you have a dGPU installed. This limits the ability to do things like KVM GPU passthrough. I have never done BIOs modification, so I was hoping someone would be able to help. I have dumped the BIOs update from the Dell site (I am currently on) and I will attach here. I really appreciate the help!

Not bumping, just adding clarification. When I say disable the iGPU, I mean that it is not even visible to any OS. I can see the sound device, but the iGPU gets disabled from the system completely.

Edit: Other Dell Bioses have an onboard device setting that is able to enable the iGPU with a dGPU installed.

After install new graphic card ,main video output is this card ,so integrated vga be disable is normal.(Desktop doesn't like laptop platform can be auto switch vga between integrated card and graphic card ,such as when we playing game is high loading so it switch to graphic card )
If you want use kvm control  ,you should connect graphic card output to kvm switch , is it??

I can help you out to try unlocked some bios options if it exist ,but the bios dump that you attach is useless ,i need real bios dump.

Use this tool to dump current bios and attach it.(Run dump.bat as administrator)
I'll check it if it's possible to unlocked options.

Thank you for the reply! I will dump the bios. When I am talking about KVM, I am talking about virtualization. What I am attempting to do is disable the dGPU during the boot process in order to pass it through to a VM. In other systems, when I disable the dGPU during boot, I am able to use the iGPU for the system and then the dGPU in the VM. Anyways, off to dumping the bios thanks again.
