I solved this issue by installing the original Nvidia drivers and signing it with an individual key.
Because it's complicate, only the steps.
* Remove all nvidia packages using "sudo apt purge nvidia*"
* Download the driver from nvidia.com
* Install the NVIDIA-xxx.run package (choose sign with self created key)
* use mokutil --import /usr/share/nvidia/...to import your key
* reboot and enrolling your key into the sim (choose "Enroll MOK" on grub boot screen)
