Intel 520 Integrated Graphics Card Passthrough Issues on Proxmox

I am having issues getting my Intel 520 integrated graphics card passing through on qemu. I am using Proxmox Virtual Environment 6.2-4.

I am getting some type of fault code when starting up a virtual machine:

qemu-system-x86_64 -machine q35 -m 2G -accel kvm -cpu host \
-device vfio-pci,host=00:02.0 -nographic -vga none \
-cdrom /var/lib/vz/template/iso/Win10_2004_English_x64.iso
