I finally forced it last night to run under Vega Frontier Edition 16GB Graphic Card. What I did was installed the lower regular end 17 version professional drivers and then do the gaming mode drivers 18.8.1 if I recall. Once I did that upgrade from there to the 18.12.2 gaming drivers. I end up needed to do a clean driver installed because it was being odd about running the Radeon setting menu window. Eventually the system took it and was happy. I would advice not to give up to anyone having issues installing these drivers because your GPU should be able to run it. I did use the AMD Clean utility from within the driver folder to make all this happen as well but you can use other tools like DDU. I was surprise it worked because originally the GPU software doesn't see anything beyond 18.8.1 on my end. Keep in mind this is also a Vega Frontier Edition that is water-cooled and flashed to the Liquid Cool version of the card with a clock of 1700MHz as max over the 1600MHz on the air edition one.
