#before

resource "aws_eks_addon" "aws_ebs_csi_driver" {
  cluster_name                = "some_cluster"
  addon_name                  = "aws-ebs-csi-driver"
  resolve_conflicts_on_update = "OVERWRITE"
  service_account_role_arn    = "some_role_arn"
}

#after

resource "aws_eks_addon" "aws_ebs_csi_driver" {
  cluster_name                = "some_cluster"
  addon_name                  = "aws-ebs-csi-driver"

  pod_identity_association {
    role_arn        = "some_pod_identity_role_arn"
    service_account = "ebs-csi-controller-sa"
  }
}

Steps to Reproduce

Create aws eks addon with service_account_role_arn then change it to use pod identity with deleting service_account_role_arn and adding pod_identity_association.
The terraform apply after changing addon from using IRSA to Pod Identity crashes
