**Tell us about your request**
How can I add the tags to the EFS access points using the EFS CSI (AWS managed EKS add-on)?

I am following this guide: https://docs.aws.amazon.com/eks/latest/userguide/efs-csi.html

I can do that with the helm chart: https://github.com/kubernetes-sigs/aws-efs-csi-driver/blob/master/charts/aws-efs-csi-driver/values.yaml#L58

**Which service(s) is this request for?**
EKS

Start with the EKS EFS CSI driver guide and compare its AWS-managed add-on configuration with the Helm chart values linked in the issue. Done means the AWS-managed EKS add-on provides a documented way to add tags to EFS access points.
