LimeSDR switching to RX2_L antenna, soapy "nchan=2" argument

Has anyone successfully switched LimeSDR receive to RX2 antennas? Normal LNAL/LNAW/LANH switching works but how to access the second channel?
I generally assumed SATNOGS_DEV_ARGS (Radio device arguments) should be “nchan=2” to end up with something like this:

“soapy=0,driver=lime,nchan=2”

Still, I seem to lack something as RX2 antenna ports are not activated, anyone can comment further?
