Alternatively, switch to CCO Manual mode or Passthrough mode. If mode migration is not immediately feasible, manually restrict the IAM policies on CCO-provisioned IAM users by adding tag-based conditions scoping destructive actions to resources tagged with kubernetes.io/cluster/\u003cinfraName\u003e=owned. For S3 actions, restrict Resource to the specific registry bucket ARN rather than \"*\". Enterprise defense-in-depth: deploy AWS Service Control Policies (SCPs) to deny destructive actions from non-approved principals, and apply IAM Permission Boundaries to CCO-created users."
