Deleting a custom endpoint
Delete a custom endpoint using the Amazon Web Services Management Console, Amazon CLI, or the Amazon RDS API.
To delete a custom endpoint with the Amazon Web Services Management Console, go to the cluster detail page, select the appropriate custom endpoint, and select the Delete action.

To delete a custom endpoint with the Amazon CLI, run the delete-db-cluster-endpoint command.
The following command deletes a custom endpoint. You don't need to specify the associated cluster, but you must specify the region.
For Linux, macOS, or Unix:
aws rds delete-db-cluster-endpoint --db-cluster-endpoint-identifier
custom-end-point-id
\ --regionregion_name
For Windows:
aws rds delete-db-cluster-endpoint --db-cluster-endpoint-identifier
custom-end-point-id
^ --regionregion_name
To delete a custom endpoint with the RDS API, run the DeleteDBClusterEndpoint operation.
