Automatic gain control (AGC) on analog RX path

Hello everybody,
today I need your help with the analog signal pre-processing on the LimeSDR USB. Is it possible to activate automatic gain control on the analog part of the RX path? This is because we have a large input range (20mV to >2V) for our measurements and of course we want to use the whole range of the ADC for better signal resolution.
Unfortunately I have not found anything in the various documentation on this topic.
Maybe someone can point me in the right direction…

best regards
