Dell Precision R7960 Rack - Firmware Update Best Practice

I have a Dell Precision R7960 Rack workstation and would like to keep the devices firmware updated as often as I can. However, unlike the R740's I have, the device cannot have updates managed by Dell OpenManage or via the LLC (selecting Dell website as the source). How do I manage this? Would SupportAssist be able to take care of it or would I need to install each update individually from the support page for the device?

Thank you
