To add: for Navi 10 (RX 5700/RX 5700 XT) there's currently a patch available at Level1Techs[1] which force the card to enter and exit Bus Active, Chip Off (BACO) which essentially resetting the card.
I have been using this patch with my VFIO setup ever since the author made it available and has been working quite reliably for me with my RX 5700 XT reference card. v1 patch sometimes stuck in weird state after BACO but usually it could be fixed by sleep the machine and wake it up. I have not experience any issues with v2 patch so far.
