Install lunar iso into Dell Precision 7680. Then install ubuntu-drivers-common 1:0.9.7.1.2 from proposed channel.

ubuntu@ubuntu-Precision-7680:~$ ubuntu-drivers list
ubuntu@ubuntu-Precision-7680:~$ sudo cp /tmp/custom_supported_gpus.json /etc
ubuntu@ubuntu-Precision-7680:~$ cat /etc/custom_supported_gpus.json

      "name": "TEST 28B9",
      "branch": "535.113",
      "features": [

  ]
}
ubuntu@ubuntu-Precision-7680:~$ ubuntu-drivers list
nvidia-driver-535, (kernel modules provided by linux-modules-nvidia-535-generic-hwe-22.04)

System can use ubuntu-drivers to list package by adding customized JSON file. With command ubuntu-drivers install, Nvidia related packages can be added. After system reboot, Nvidia GPU work as expected.
