 * If you use {rh-rhacm} observability, the CR must be augmented with appropriate `additionalAlertManagerConfigs` CRs to forward alerts to the hub cluster.
 
+{rh-rhacm} observability combines its default data values with the monitoring configuration ConfigMap CR provided as part of the cluster tuning reference CRs.
+This merge results in the policy becoming non-compliant. 
+To ensure that the provided configuration is not overwritten or merged with {rh-rhacm} data values, you can disable the {rh-rhacm} management of this `ConfigMap`` CR . 
+This keeps the policy compliant. For more information, see the Observability section of Telco hub reference design specifications.

 * Reduce the `Prometheus` retention period to 24h.
