OME and client update catalog

Hi,

Possibly a really dumb question, but can't find an explicit answer:

Can OME update firmware and drivers on Optiplexs, Latitudes, etc or only monitor them? An Optiplex 9010 with OMCI installed (and a nice green tick in Devices) that I know has an out of date BIOS doesn't appear in OMEs Non-compliant systems list.

I'm using ftp://ftp.dell.com/catalog/catalog.cab as my online source.

If only monitor, is SCUP my only option? Had some bad experiences recently with the Dell catalog breaking my WSUS (recreatable, but haven't got the time at the moment to go through it all again and report it properly).

Thanks

Gary
