Access to Open-Source-Firmware on 3DR RADIO TELEMETRY

This topic refers to the 3DR Radio with the part number: MBS-Z-163.

The radio transceivers use the MAVLink protocol, which is open source. For our application, we want to send sensor data (6 measurements per reading) at 400 Hz from an external sensor on a drone to some kind of ground station. Initially, only this data should be transmitted, and no control commands should be sent to the drone. We wondered how we can access the firmware of the radio transceivers. Is this simply done through GitHub or similar platforms, or is there another way to directly access the on-board software?
