+Autopilot cluster modules now set `enable_gcfs` to `true` by default to
+aligned with TPGv6. To maintain the previous provider default behavior, set
+`enable_gcfs` to `null`.

 The `monitoring_observability_metrics_relay_mode` parameter has been
 replaced with `monitoring_enable_observability_relay`.
