How can the connection string be configured on an IoT Edge device?

Configuring the connection string on an IoT Edge device can be effectively achieved by running a script remotely on the device. This method allows you to directly execute commands or scripts that modify the device's configuration settings, including updating the connection string used to connect to the Azure IoT Hub.

When implementing changes like this, ensuring that the configuration change is done remotely is particularly useful in scenarios where there are many devices needing configuration at scale, ensuring consistency across deployments without the need for manual intervention on each device.

Other methods listed may suggest alternatives for managing or updating configurations, but they don't provide a direct and streamlined mechanism for altering the connection string on IoT Edge devices as efficiently as running a remote script does. The Azure portal and IoT Hub settings can manage higher-level settings or monitor devices but aren't typically involved in directly modifying the connection string on the device itself.
