Connect to Nvidia Jetson Nano with VNC

I am trying to connect to my Jetson Nano with VNC in order to run my OpenCV program. The Jetson is not connected to a display.
I followed the instructions present on L4T-README (when plugging the Jetson to my computer) but apparently vinoserver won’t start without a display.
I also unsuccessfully tried different methods found on this forums or other websites such as installing xserver-xorg-video-dummy.

Can someone help me?

Thank you
