Trying to passthrough the IGPU on a 12600k for a single windows 11 VM and use it on a displayport/hdmi (like a physical machine). I search all around, specially follow this guide but couldnt make this work.

CPU: i5-12600k
MOBO: Gigabyte z690 AX UD
Proxmox 8.2.7 (fresh install)
On every post i read this command shows the specific graphics (in this case is it should be UHD Graphics 770) but it wont appear.
Code:
lspci -nnv | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation AlderLake-S GT1 [8086:4680] (rev 0c) (prog-if 00 [VGA controller])

This is the menu when chosing the device

/etc/modules
Code:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

/etc/default/grub
Code:
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
GRUB_CMDLINE_LINUX=""

I´m doing something wrong or is a hardware limitation?
