I attempted to recreate your issue with my own x570 Taichi and a pair of RX 580s
but I wasn't able to reproduce it. I updated to 5.69 and installed all the drivers
etc but the system didn't exhibit the issue you describe. It may be because I don't
have the same additional hardware, I have a Ryzen 5 3600x in my Taichi at the moment
and I don't have an A750 to throw in. I am afraid that is about all I can do. I
am just the moderator here so I don't have access to the same kind of resources
as ASRock's Tech Support staff. I had hoped that the fact I coincidentally also
own an x570 Taichi would allow me to recreate the issue but no dice.

Good luck and let me know how it goes with ASRock's Tech Support department.
