Are you sure? 
Either way, your request seems to be more of an XY Problem. Please feel free to create a topic in Gaming if you need help with a certain game. However, before you do, please see the pinned topic for helpful resources.
By the way, I play games via Steam, Lutris and Epic Games Launcher and have never needed to install DXVK, VKD3D, etc. as a system package because there’s no need.
We will not be adding a DXVK package to the repos at this time.
