Headless Jetson Nano Capabilities

If I were to make my Jeston Nano “headless” and connect it to my laptop, would I still be able to run ROS and see Rviz simulations?

Please try to setup vnc with below virtual screen in xorg.conf.

Setting the Desktop Resolution
  ----------------------------------------------------------------------
  
  The desktop resolution is typically determined by the capabilities of the
  display that is attached to Jetson. If no display is attached, a default
  resolution of 640x480 is selected. To use a different resolution, edit
  /etc/X11/xorg.conf and append the following lines:
  
  Section "Screen"
     Identifier    "Default Screen"
     Monitor       "Configured Monitor"
     Device        "Tegra0"
     SubSection "Display"
         Depth    24
         Virtual 1280 800 # Modify the resolution by editing these values
     EndSubSection
  EndSection
