Possibly the iGPU gets automatically deactivated as soon as there is a dGPU present. So, I would check the bios/UEFI for an option regarding this.

(This assumes, that the iGPU works at all. You might want to verify this by e.g. removing the dGPU and connecting a monitor to an onboard display output; if not already done.)

That's probably it. Additionally, you might need to connect a (powered on?) display to one of the iGPU outputs to get it to be enabled.

Thank you for the help! There is indeed an option in the BIOS settings that prioritizes the use of the GPU or the iGPU. It was set to "automatic" which is why it didn't show up, but I changed it to the first option which is iGPU. Now it appears in Proxmox.
