NB: the vncserver command used within the PuTTY (SSH) or GtkTERM (Serial) terminal windows within the screenshots in the following examples is a symbolic link to vncserver-virtual as discussed in this forum thread: https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=200196&p=1598431&hilit=vncserver+virtual#p1598396 and shown in the terminal "extracts" below including how to access the man pages (shown in part):

NAME
       vncserver-virtual - VNC® Server in Virtual Mode

SYNOPSIS
       vncserver-virtual [OPTION...] [:DISPLAY]

       vncserver-virtual [OPTION...] COMMAND

DESCRIPTION
       vncserver-virtual  starts  VNC Server in Virtual Mode, to create a virtual desktop
       and provide a dedicated workspace for connected VNC Viewer(s). A  virtual  desktop
       persists  until  VNC Server is explicitly stopped, even if the user starting it is
       logged out, or all VNC Viewers disconnect. It is entirely independent of the  con‐
       sole  of  the  host computer; neither the desktop of the currently logged on user,
       nor the login screen, are available to connected VNC Viewers.
