Polarix 22 XL passthrough VM Windows 10

[ousank]

Hello,

I'm really new into the proxmox environment.
I've succefully configure proxmox and begin to launch some VMs, into my HP Spectre (laptop)

Now, I would like to passthrough the internal GPU (AMD Vega M GL) to the Windows 10 VM, but after the boot of the VM, i get a "43 error code", even if install correct GPU drivers...

Any help would be very appreciated

Here some conf I actually have on the host :
file:
/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt vfio-pci.ids=8086:1901,1002:694e"

command :
lspci -nnv
