Hi Donna, I regret that the answer you are looking for is, “You can’t.”
See this: http://osxdaily.com/2016/01/04/stop-ios-software-update-notification/ Read all the comments too; fun stuff. The best options you have are to either go to cellular full-time, leave the downloaded updates on the devices and simply keep ignoring them, or install a cache on the network that would at least prevent redundant downloading. But as for the off switch that you seek, there is sadly none. :( Cheers, Sabahattin -- The following information is important for all members of the Mac Visionaries list.
