	//   - None – Amazon EKS doesn't change the value. The update might fail.
	//   - Overwrite – Amazon EKS overwrites the changed value back to the Amazon EKS
	//   default value.
	//   - Preserve – Amazon EKS preserves the value. If you choose this option, we
	//   recommend that you test any field and value changes on a non-production cluster
	//   before updating the add-on on your production cluster.

	// node IAM role (https://docs.aws.amazon.com/eks/latest/userguide/create-node-role.html)
