SCCM 1810 support for integrated (non SCUP) Third-Party Software Update Catalog

Does the server catalog ( https://ftp.dell.com/catalog/DellSDPCatalog.cab) support the integrated (non SCUP) offering within SCCM 1810 ? I did manage to add the catalog then publish and deploy but have yet to be able to successfully install any update on any client. SCCM software updates are set to allow SCCM to manage the certificates and all other updates such as Adobe and Microsoft get installed ok on the clients.
