Short answer - yes!
The device doesn't know anything about enrollment groups - the device sends its registration Id and authentication data to DPS. DPS figures out which allocation group or individual enrollment to use.
For more info, see https://docs.microsoft.com/en-us/azure/iot-dps/about-iot-dps
For C DPS registration samples, see https://github.com/Azure/azure-iot-sdk-c/tree/main/provisioning_client/samples
group enrollment is supported by C SDK.
You can leverage this MSFT doc as reference for provisioning X.509 devices using enrollment groups.
