While creating Unity Catalog external location from Data Bricks UI or from a notebook using "CREATE EXTERNAL LOCATION location_name .." a connection is being made and rejected from control plane to the S3 data bucket in a PrivateLink enabled environment where AWS S3 data buckets (other than Unity Catalog/Meta store bucket which is accessible from control plane) are only accessible from the Customer Managed VPC of compute plane and no connection from control plane is allowed to AWS data buckets.
How connection form control plane to external bucket can be avoided or what is the minimum access control plane needs on external buckets while creating external location.
