Auto reboot rig with GPU hanging?

Good day,
im looking for a way to auto reboot the complete rig if one GPU hangs. if i have the watchdog active (wd 1) the rig freezes frequently, so i have it deactivated and reboot manually if i see one card down.

i tried to inser (-r 1) but it doesn’t reboot the rig when a cpu fails.

Thank you for your Help!
