On the 30AG radio, RX diversity is greyed out when TX diversity is disabled. Can TX and RX diversity be set independently?

For the 30AG radio, RX diversity follows the TX diversity setting.  Therefore, when TX diversity is enabled, RX diversity will also be enabled.  When TX diversity is turned off, RX diversity will also be turned off.  Some of our other radios, such as the 40 series radios allow for TX and RX diversity to be set independently.
