 ## Opt out of diagnostics reporting
 
+{{site.data.alerts.callout_info}}
+Diagnostics reporting is required for [**Enterprise Trial** or **Enterprise Free** licenses]({% link {{ page.version.version }}/licensing-faqs.md %}#types-of-licenses). Therefore, the cluster setting `diagnostics.reporting.enabled` is ignored on clusters with these licenses. The following opt-out methods apply only to clusters with an [**Enterprise** license]({% link {{ page.version.version }}/licensing-faqs.md %}#types-of-licenses).

 ### At cluster initialization
 
 To make sure that absolutely no diagnostic details are shared, you can set the environment variable `COCKROACH_SKIP_ENABLING_DIAGNOSTIC_REPORTING=true` before starting the first node of the cluster. Note that this works only when set before starting the first node of the cluster. Once the cluster is running, you need to use the `SET CLUSTER SETTING` method described below.
