Selected Answer: A

Answer is "A". This is exactly what you need to do See https://github.com/Azure/iotedge/blob/main/edge-agent/README.md ConfigSource May be set to "twin" or "local". When set to "twin", the edge device twin is used as a configuration source for modules. When set to "local", a file (config.json) is used as a configuration source for modules. A custom configuration JSON file can be used by bind mounting a directory containing the custom configuration file into the edge agent container and specifying the path to the configuration file in the container using the LocalConfigPath environment variable. DeviceConnectionString must be set to a device connection string if ConfigSource is set to "twin". LocalConfigPath Path to the custom configuration JSON file used as the configuration source in the "local" mode.
