Synergy Mode --- All other function of Synergized device disabled?

hi, I am deploying a project and use Balance 20X as synergy controller to control the Br1 5G Mini, but after 5G Mini synergized, it seems we can not configure the wifi, port setting etc. The 5G Mini act as a pure modem.

In this case I am wondering if there is any advantage of using synergy mode?
