No. Azure's built-in SFTP support requires Data Lake Storage Gen2 with the hierarchical namespace turned on. You can choose it when creating an account, or upgrade an existing one in place - but the upgrade is one-way, pauses writes while it runs, and cannot start while the account holds page blobs or has snapshots, soft delete, versioning or immutable storage switched on. DocEvent connects to a plain Blob container as it stands, and also supports Data Lake Gen2 and Azure Files if that is what you already use.
