Dell Catalogue Sync for MSEndpointMgr Driver Automation Tool for SCCM

Hi we use this tool for automation of hardware support in SCCM for new Dell models.  The tool synchronises Model information from https://downloads.dell.com/catalog/DriverPackCatalog.cab and for some reason I do not find some of the newer Dell models included in this catalog.  For example:

Dell Pro Tower Plus QBT1250

Dell Pro Max Tower T2 FCT2250

I don't know why these models are not included in this catalogue file, does someone know why.?

Many Thanks
