How do I switch to amdvlk for Doom the Dark Ages

I'm having performance issues with Doom the dark ages with the default drivers Mesa so I want to try amdvlk on it but don't know how to properly do it, like I know you put a certain command in the launch options but I don't know where to put the files like JSON and so, can anyone tell me how to do this and will I see an improvement in performance on Doom dark ages?
