Nvidia rtx 4090 passthrough problem


I want to do GPU Passthrough to Windows 10 Machine on Proxmox Virtualization.

I followed the instructions in the link PCI Passthrough - Proxmox VE

But when I run it in PCI-Express Mode, the virtual machine freezes or does not boot.

When I run it in PCI mode, the GPU-Z output is as attached, and the video card does not appear in the task manager.
