Find the Device IDs

# The first value (26:00.0) is the BDF ID, and the last (1002:6810) is the Device ID
$ lspci -nn | grep "VGA\|Audio"

For every command below, replace the device IDs with your owns.

Upgrade grub

$ sudo nano /etc/default/grub
# Add the following to `GRUB_CMDLINE_LINUX_DEFAULT` section
iommu=pt amd_iommu=on vfio-pci.ids=1002:67df,1002:aaf0 video=vesafb:off,efifb:off # if AMD
iommu=pt intel_iommu=on vfio-pci.ids=1002:67df,1002:aaf0 video=vesafb:off,efifb:off # if Intel
$ sudo update-grub
