Default [Q] (Q) Flashing .zip file through ADB without any hardware key?

Hi guys, I'm trying to find the ways to flash update.zip file to my developers board, IFC 6410 from infoce computing,

and I have made a way to boot in recovery mode by ADB, but wonder how I can install update .zip file without any hardware key, as the board doesn't have any of the volume and power key.

is there specific ADB command to install zip file???
