A40 missing PCI devices

The problem I’m running into is I’ve installed the chipset drivers and nvidia drivers for the CPU and a40 respectively,and I’m seeing a40 in the device manager but am still seeing a bunch of unknown PCIe devices. The GPU doesn’t show up anywhere on the system (task manager, hyper-v virtualization) and I’m at a loss for what else to try at this point. Not sure if a40’s have some extra configuration or drivers needed, or if I’ve done something along the way incorrectly. Please let me know if you have any ideas.
