on an intel system using the SGX driver allows cyberlink power DVD to play 4k disks, is there a similar driver for a ryzen system?
This is not an issue we are aware of. HDCP protection is a feature of the display driver not the GPU.
HDCP is solely used over HDMI and I'm using the display port on the Graphics card to my 4k Monitor, so I don't understand why I can't play a 4k blu ray disk?
Display Port supports both HDCP as well as DPCP (DisplayPort Content Protection).
