No. Feature access, storage enablement, retention, and deletion are separate questions. An access refusal establishes that the current request cannot read the data; it does not by itself confirm erasure. Disabling a feature is not a substitute for a verified deletion request.
Review the storage state and the actual result of any retention or deletion change. If you need to confirm deletion, ask support about that specific operation and period. Do not enable unrelated storage or change credentials merely to infer whether data still exists.
