Unable to enable IGPU

Posting in Hardware since I can’t find the relevant setting/section in BIOS. Please let me know if inappropriate.

CPU - From 3600X to 5700G (Confirmed this CPU is on the Compat list for my Mobo)
MoBo - MSI Meg Unify X570
Bios Version - Latest as of 8/9/24 (2 versions after 5000 support was added)
GPU - Nvidia 3080. This is still connected since I need to change some configs and confirm functionality before removing it.

I’m trying to remove a GPU from my Proxmox setup. I upgraded the BIOS to the most recent version and then swapped the CPU. The CPU works fine, but the IGPU isn’t visible in Promox. It looks like there should be a setting in BIOS > Advanced > Integrated Graphics Accelerator to enable the IGPU with a discrete GPU connected. I don’t have this section. Poking around the BIOS I haven’t been able to find any settings that would pertain to IGPU.
Searching this issue, I found other users with similar situations but no solution. With the CPU being on the compatibility list I’m hoping this is just a setting somewhere. I am starting to wonder if that compatibility list only applies to the CPU functionality and not the IGPU.

Any help would be greatly appreciated.

I chatted with MSI support, who confirmed this should work. ¯_(ツ)_/¯
I tried removing the external GPU to see if was an order of operations thing, but that just resulted in no display out.

I finally just swapped the server mobo with my desktop mobo and everything worked correctly.
