You don't have problems with AMD display driver components.
If you have driver problem as you wrote, this way will shut down your system smoothly.
Device Manager > Display Adapters > AMD Radeon VII > Right Click > Disable device
And then try shutdown to the system...
If the system shuts down smoothly, please contact AMD to report the situation.
Edit: Device Manager > Display Adapters > AMD Radeon VII > Right Click > Enable device
With this way, you can enable the GPU...
I'm getting into the conversation late. I don't know that I have a cure for this but I may have a partial explanation on why Win 7 and Win 10 act differently. First and foremost, Win 7 existed long before the generation of hardware you are using. The OS doesn't have the capacity to leverage CPU features in your system because those things hadn't been built into the CPU back then. The same applies to features of the motherboard. So what you may likely be seeing is something that is leveraged in the newer OS but didn't even exist at the time Win 7 was written.
That being said, I know you referenced looking at different video BIOS and motherboard BIOS. I think you should focus on the motherboard and its BIOS more so than the GPU. Check with the motherboard manufacturer to see if there is an update from them. Also, look at the motherboard forums and see if others are having something similar with that motherboard. There may well be others with similar issues but with a different GPU. Don't narrow the search to just the AMD R 7.
Finally, there is a registry setting in Windows that controls how long Windows wait for services and tasks to terminate when doing a shutdown. I don't have a link handy but I know the registry entries allow the defaults to be overridden. Trying that might help solve this. And if this were me, the server admin background would already have me looking at the Windows Event Logs. There is a treasure trove of stuff in there. A lot of noise for sure, but you are likely to find the culprit by scrolling through those logs.
