Is 24 bit possible through the analog input?

I’m running a Rpi3 with a Hifiberry DAC + ADC pro HAT over wifi. Is the analog input within Volumio only limited to 48khz 16bit? I know that the hifiberry is capable of 192khz 24bit through the analog in. Is there a setting that I can flip to increase the audio input quality? Perhaps connecting via ethernet?
