Authentication of Accessing ATP DB objects in OIC without storing creds in OIC Connection

We have an ask from one of our client's IT security team that we do not store the ATP wallet and credential details within the OIC connection.

Instead, is there a way to dynamically retrieve these details from the OCI vault during the integration and pass them directly when connecting to ATP or any alternative approach for the same ?

Please let us know if anyone has encountered a similar requirement and how it was addressed.
