ADRV Power Supply for Single channel Operation (TX1 & RX1 only)

PDF

Attached in PDF is power supply to the chip for using only one Transceiver channel, i.e., TX1 & RX1. Hence power supply pins pertaining to TX2 & RX2 are left floating in order to save power. Is this configuration fine? If not, what has to be done? Thank you in advance!
