+### Delete unenrolled agents [delete-unenrolled-agents-setting]
 
 After an {{agent}} has been unenrolled in {{fleet}}, a number of documents about the agent are retained just in case the agent needs to be recovered at some point. You can choose to have all data related to an unenrolled agent deleted automatically.
 
 Note that this option can also be enabled by adding the `xpack.fleet.enableDeleteUnenrolledAgents: true` setting to the [{{kib}} settings file](/get-started/the-stack.md).
 
 To enable automatic deletion of unenrolled agents:
 
-1. Go to **{{fleet}} > Settings**.
-2. Under **Advanced Settings**, enable the **Delete unenrolled agents** option.
+1. Go to **{{fleet}}** > **Settings**.

+If you have [agentless integrations](/solutions/security/get-started/agentless-integrations.md) deployed, you can enable the **Show agentless resources** option to display related resources such as agentless agents and policies for inspection and diagnostics purposes.

+To display the agentless resources in the agent and agent policy lists:
+
+1. Go to **{{fleet}}** > **Settings**.
+2. In the **Advanced Settings** section, enable the **Show agentless resources** option.
+
+Note that you can view and request diagnostics for agentless agents, but you cannot upgrade, unenroll, or reassign them.
