AWR1843: Decreasing RX gain below 24dB?

Hi, is there any method to decrease RX gain in AWR1843 below 24dB overall gain? As I understand, 24dB overall gain comes from 26dB of RF frontend gain and -2dB of IF/VGA gain. We are mostly interested in decreasing RF frontend gain below 26dB to avoid some ADC saturation that we are experiencing.

Thanks!
