40 pins header support for nvidia nano

Hi There,

i am considering to build a prototype for an acoustic sensor platform (for now oriented in intent recognition) based on a NVIDIA nano device.
I see there is here a similar question with no answer for the tx2 board.

Apparently, it is possible to configure the nano (and other nvidia board, I guess)
Configuring the 40-Pin Expansion Header and eventually create your own configuration

I am not really an expert here, so anyone with experience that can point out to same resources to configure the 40pins or perhaps someone has already made it.

Thanks,
Lawrence
