The goal of this is to prevent the Linux kernel from loading drivers that would take control of the GPU. Because of this, it is necessary to have two GPUs installed and functional within your system. One will be used for interacting with your Linux host (just like normal), and the other will be passed-through to your Windows guest.
Assuming your passthrough GPU VGA device is now showing vfio-pci as the kernel driver, you may still see something other than vfio-pci in use on your planned GPU passthrough audio device. If that's the case for you, here's how I managed to fix it.
