Unfortunately, Teltonika devices do not support Azure IoT Edge.
That would require additional development and certification from Microsoft. This question has been looked upon already and it has been decided to not pursue Edge Managed (Azure IoT Edge) certification. The same answer applies for Micro Agent for IoT Edge for Security and Defender IoT since these features are built upon IoT Edge functionality.
Additionally, it would require devices to implement a container engine support e.g. Docker, which Teltonika devices currently do not support, as Docker itself requires a lot of storage space (50MB+), so that would most likely require a custom solution the devices.
