Black screen on Ubuntu 20.04 with GP107GL [Quadro P620] and nvidia-driver-460

I’m trying to use a Nvidia driver instead of “nouveau” on Lenovo P340 Tiny without success even following the directions of Lenovo support.
After installing the driver and rebooting PC I see black screen with cursor blinking up.
The operating system starts and I can access other TTYs (Ctrl+Alt+Fn)

From TTY with command
lshw -c video
I notice that in configuration there is no driver:
configuration: latenct=0

Thank for any help. (138.5 KB)
