How to Set SISO using LMS API

Dear All,
I tried to lower the current draw and Thermal Output of the LIMESDR-USB.
I use only the RX1 channel and in order to do so I used:

LMS_EnableChannel(device, LMS_CH_RX, 0, true);
LMS_EnableChannel(device, LMS_CH_TX, 0, false);
LMS_EnableChannel(device, LMS_CH_RX, 1, false);
LMS_EnableChannel(device, LMS_CH_TX, 1, false);

Is this the correct way to Turn off RX2, TX1, TX2 and use RX1 in SISO mode?
