Firmware update via the API

Hello, is it possible to update the firmware on the Transit Duo with the 8.1.2 via the API.
The reason is that this may only take place at certain geofencing locations.

You can schedule the upgrade via InControl2 and Geo fencing is support for the firmware policy.

We use a self-hosted InControl2, is it also possible there and if so, how do I get to the settings?
