UHD Graphics 730 with RTAI Kernel

The latest RTAI Patches are for Kernel 5.4 but the Support for UHD 730 in the i915 Driver has been added in 5.11 (I think).
Any ideas how to get the Driver working in the 5.4 Kernel?

I'm using a Core i3 14100T on an ASUS Q670EI-IM-A Board.

Thanks

It works well in text mode.

I don't think there would be any Mini ITX Boards with onboard GPU and we don't have the space for PCIe GPUs in the system.
