HQ player with CX/EX and Roon

I have successfully used HQ player on the EX but I want to try running it on the CX to take advantage of the more powerful compute power. I want to try upscaling to DSD.

Can someone please walk me through the exact settings I need to make on the CX and EX (ideally with screenshots).

It needs to be set up with Roon as the front end.
