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

Hi guys, I'm trying to find the ways to flash 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???
