i had to follow this to get the nv kernal driver working again. After that i had to shutdown and power off the unit. now gpu is showing up. Still working on the nvidia drivers, they still appear broken.
Update - i had to uninstall the nvidia drivers, reboot then install the drivers again. It took for ever but i think i am finally back up with gpu and still on current FW. That was like 4 hours wasted….
PS dont forget to reset the gpu usage under hardware
