           Create explicit service accounts wherever a Kubernetes workload requires specific access
           to the Kubernetes API server.
+          K3s makes an exception for the default service account in the kube-system namespace.
           Modify the configuration of each default service account to include this value
           automountServiceAccountToken: false
           Or using kubectl:
-          kubectl patch serviceaccount default --patch '{"automountServiceAccountToken": false}'
+          kubectl patch serviceaccount --namespace <NAMESPACE> default --patch '{"automountServiceAccountToken": false}'
