That appears to be hard coded.

                # If running, then all is well and break out of loop
                kill -0 ${VNC_PID} 2>/dev/null && break
              done
          
              # If we fail to start it after so many tries, then just give up
              kill -0 ${VNC_PID} 2>/dev/null || clean_up 1
          
              # Parse output for ports used
              display=$(echo "${VNC_OUT}" | awk -F':' '/^Desktop/{print $NF}')
              port=$((5900+display))
          
              echo "Successfully started VNC server on ${host}:${port}..."
          
              #{super}
            EOT
          end
          
          # Run the script under the VNC server's display
          def run_script
            %(DISPLAY=:${display} #{super})

Min and max ports only apply when you’re looking to find_port. So it doesn’t appear to be used here in the noVNC case.
