Subpanel for ADU in separate building

This is going to be a brand new security install. No existing wiring but I was planning on trying to install the wiring myself.

Is it possible to install a subpanel in the ADU and just run a single connection from the panel to the home mainboard?

Thank you!

 the answer to this for anyone interested, is NO.

Konnected pro boards does not have extension boards or sub panels


it is easy enough to just purchase another pro board and run it there independently from the main home.
