I’m developing an IoT device system and facing the challenge of certificate provisioning. I want to implement a provisioning system that runs on the device’s first connection to the internet. We plan to use MQTT for device-to-cloud communication.

I found that Azure DPS can generate certificates, but its usage is limited to Azure IoT Hub. Additionally, the IoT Hub documentation recommends using Event Grid if MQTT is desired, as it supports all the necessary features.

So, what should I do if I follow that recommendation and use Event Grid? How can I automatically generate certificates in that case?
