Just made a patch that patches in polaris the same way for vega on blender 3.4.0 alpha for linux
as linux can run rocm 5.2.1 (22.20.1) flawlessly on linux using this env var
ROC_ENABLE_PRE_VEGA=1
and hip works quite well on those cards (outside blender)

yes the renders are broken , but this is a proof of concept ,
and also blender fault rather than a driver fault
YES it can be done , but the dev team just doesn’t want to .
