If you own a NUC "formerly" by the name of "Hades Canyon", you've most likely run into the same issue I have -- Graphics driver support is at rock bottom at the time of writing. Here's how to update to the very latest drivers AMD has to offer.
DISCLAIMER: I take no responsibility for damage to your hardware. You do this at your own risk. That being said, we want the latest and greatest, so moving on...
1. Download the latest "officially supported" software from AMD's website -- 20.4.1 -- and install normally --
2. Download the latest Adrenalin software from AMD's website --
... Choosing "Graphics", "Radeon™ RX Vega Series", "Radeon™ RX Vega Series", and "Radeon™ RX Vega 64". Click "Submit".
Expand your operating system, and under "Adrenalin 2020 Edition X.X.X Optional", click "Download*".
3. Deploy them as intended, by launching the executable, and unpacking them. By default, they will extract to "%SystemDrive%/AMD".
4. Manually update your Display Driver by launching "Device Manager" ("WinFlag" + "R", followed by "devmgmt.msc") and right-clicking "Display adapters > 'Radeon RX Vega M GH/GL'", followed by "Update driver".
5. Choose "Browse my computer for driver software", followed by "Let me pick from a list of available drivers on my computer".
6. Specify the location of the directory where the relevant *.inf files are located. --
In the field "Copy manufacturer's files from", input the full path to the drivers -- don't click "Browse..."! -- which should be the "WT6A_INF" folder, located, as an example, in "%SystemDrive%\AMD\Win10-Radeon-Software-Adrenalin-2020-Edition-X.X.X-XXX\Packages\Drivers\Display\WT6A_INF".
7. Once you've entered the correct path, click "OK", and a list will be populated with available drivers to use. Select the first "Radeon RX Vega" you can find in the list -- in my case there were two to choose from, so I picked the first one. It will prompt you a warning, click "Yes" to proceed.
8. Once installed, that's the driver done. You've successfully got the most recent updated driver configured on your computer. If you've no intention of using AMD's Adrenalin management software, and just want the most recent driver, and don't intend to overclock, you can stop here. Congrats! For everyone who wishes to proceed with the Adrenalin software...
9. Edit the registry value "HKEY_LOCAL_MACHINE\SOFTWARE\AMD\CN\DriverVersion" --
Adrenalin software support for "Radeon RX Vega M GH/GL" ended with version 20.4.1, which was available the first of April, 2019 -- and what now feels like an out-of-season April fool's joke.
Now, you can trick your installed Adrenalin software to work, with your most recent driver, by editing the registry key "DriverVersion" located in "HKEY_LOCAL_MACHINE\SOFTWARE\AMD\CN" -- you can access this with the "Registry Editor" ("WinFlag" + "R", followed by "regedit.exe") -- this needs to match whatever driver version you're using.
You can find the driver version you've installed, by again going to "Device Manager", followed by your driver, which should now list as "Radeon RX Vega", right-clicking "Properties", and then under the "Driver" tab, finding your version listed. Once you've edited the registry key to this value, close the registry editor, and reboot your PC. AMD's Adrenalin software should now launch as normal.
