If the OCLP patch does not work when iGPU is enabled, then we can disable iGPU and use “FeatureUnlock.kext” from the acidanthera GitHub repository. Simply Google for this kext.

Both the answer and the result were very fast. Thank you very much. All problems solved. One small question, the sidecar performance is a bit bad. The image is a bit shaky. Is this the best we can have or is there an extra setting that can be optimized?
Have you enabled DisableIoMapperMapping quirk?
I think it's best use iGPU for Sidecar function if possible.
I tried enabling it after you mentioned it, which at least eliminated the wifi disabling issue, but I didn't see any improvement in sidecar performance. By the way, I also deactivated the feature unlock kext before I tried this. How can I be sure if the iGPU is working as headless? Thank you.
After spending a lot of time on this I think I got everything figured out (cross fingers). I ended up removing SSDT-UIAC-DESIGNARE-Z390-FD-DEFINE-R6-V3.aml and putting back SSDT-UIAC-DESIGNARE-Z390-V7D.aml because the USB port options are almost identical. "And this worked" I now have the USB ports on front of case tied to HS11 and HS12 working. I disabled sleep and just have display and screensaver working which is perfect, since running a Corsair 115i AIO doesn't really allow it to sleep, plus I use it in Windows also (which is fine). Ethernet, WiFi and BT all work. So, I'm all good. The Zoom with the mouse is working now as well, must of been something bad in EFI folder.
Thank you! Had to open it up and reseat the card but the rest was a breeze.
Couple of questions about the statements in red:
Be more specific, as in the amount of dollars etc. that you can spend.
Around $300.
