+At the engine level, there is a telemetry module built into the Docker
+Enterprise Engine 18.09 or newer. It can be disabled by modifing the [daemon
+configuration
+file](https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-configuration-file).
+By default this is stored at `/etc/docker/daemon.json`. 
+
+```bash
+{
+  "features": {
+    "telemetry": false
+  }
+}

+Docker daemon will need to be restarted.
+
+```bash
+$ sudo systemctl reboot docker
+```
