I have a BOXNUC8i5BEH, the most recent BIOS update seems to have broken HDCP 2.2 and SGX detection for PowerDVD. I have been in contact with Cyberlink and have exhausted their support. They state that they are using Intel provided code to detect SGX. I have verified that SGX is enabled in BIOS and have given it the recommended memory allocation by Cyberlink. The SGX Windows Service is running, but the PowerDVD BluRay Advisor cannot detect SGX and now it is saying that HDCP 2.2 is also missing. I'm unable to watch 4k movies on my NUC any more. I'm confident that both the TV and A/V receiver have the necessary features to support it as this used to work. In addition, 4k movie playback still functions using my XBox One X.
So we can have more information about your system, Download, run, and save the results of this utility as a text file:

It is weird that graphics driver 18.104.22.16880 did not replace 22.214.171.12441.
You can use Corel Ultra HD Blu-ray check tool 126.96.36.199 instead of old CyberLink Ultra HD Blu-ray Advisor. But you need to solve HDCP 2.2 issue first.
Adjusted the amount of RAM from 1024 to 512 to the graphics card and now HDCP 2.2 is passing (weird). Would you happen to have a link to the corel tool? I tried looking for it, but couldn't find it. I contacted their support to see if I could find it, but they're busy and have to get back to me.
You can run CyberLink Ultra HD Blu-ray Advisor again and check the error code. If you get the error code -394260080, I think SGX works and you should run your PowerDVD 17 if it supports UHD Blu-ray discs.
I got the error code -394260080, but PowerDVD 20 Ultra plays UHD Blu-ray discs.
