Node js / golang server in dappnode xtreme

Hi, I bought a dappnode xtreme box and running Gnosis validators. I was wondering, is it possible to use the xtreme box as a linux server i.e., to run a node js / golang server or to use vs code inside the xtreme box? If possible how to do that? I tried adding a keyboard & monitor to the xtreme box and it shows dappnode tty1. please suggest…
