It first got enabled in radv by default here with the release of mesa 23.1.0. Before that because it was still being tested and features being worked on you had to manually enabled it with a env var RADV_PERFTEST=gpl
Edit: even tho it's technically possible to use a semi implementation with these older versions as DadSchoorse says below I'd also recommend using it with 23.1 as plenty of bugs were fixed through time.
While vulkaninfo claims that I have
graphicsPipelineLibraryIndependentInterpolationDecorationandgraphicsPipelineLibraryas supported, DXVK claims I do not.
vulkaninfo only claims that lavapipe supports those features, your old radv version does not. If you want to use GPL with your gpu you should use at least mesa 23.1.
Update your driver. :)

While vulkaninfo claims that I have
