Tesla T4 becomes primary monitor for DVI-D connectivity

I have Ubuntu 18.04.5 Desktop installed on a system with Tesla T4.
After applying the NVIDIA driver, Tesla T4 becomes the primary display for some reason.

The Tesla T4 doesn’t have a video output port, so I want to disable it.
Currently, it is avoided by executing “xrandr --output DVI-D-0 off”.

Please let me know if there is a good workaround.
