Have you tried the Manufacturer's Support site to see if they have any updated vBIOS for your GPU card?
You can see if there is a newer vBIOS at TechPowerUp Database from here: https://www.techpowerup.com/vgabios/?architecture=AMD&manufacturer=&model=RX+460&interface=&memType=...
You can download the latest AMD Driver from here: https://www.amd.com/en/support/graphics/radeon-400-series/radeon-rx-400-series/radeon-rx-460
