well, what information do you have available in your code? the device symmetric key or the IoT Hub owner key (or another key with registry permissions)?

@DavidStania have a look at the docs.microsoft.com/en-us/azure/iot-hub/… and select your case.

You can create the shared access signature using the device sdk or the service sdk.
On service sdk side, you can create a generic shared access signature i.e. with resourceuri as {IoT hub name}.azure-devices.net/devices. Check relevant link here.
On device sdk side, you can use the below image algorithm and generate the signature and use it in the code to connect to IoT Hub. For example, here is NodeJS code for device sdk which uses SAS. You can find similar examples in C# too.
So, in the above image u can use policy as iothubowner which has all relevant permissions and with that you can fetch/update/add any device information.
