I already knew you're able to disable updates the way as described above, I build my package with the "Admin users update via Adobe Update Manager" option checked. This way admins are capable of using the updates. Dont want my standard users to (are not allowed to) run updates so also would like to stop update notifications. If you choose to disable update manager, also admin users cant use updates(greyed-out)
So i only would like to stop adobe update manager to notify for updates just like the method described (and worked before cc2015)
Disable auto-updates | Application Manager | IT administrators
