I don't think there's any ability to stop the Notifications appearing within your dashboard regarding automatic firmware upgrades. If you click on the "X" this will close the notification. If you get a Network admin to re-schedule in the upgrade or perform the upgrade now this will obviously remove the notification.
My recommendation would also be to use the "Make a Wish" feature to recommended not getting firmware upgrade notifications for non-admin accounts.

It is not possible to disable this, but I can see how it would be frustrating. Thanks for bringing it to our attention.
As has been mentioned, the wish box holds a surprisingly large amount of power. If you come across anything else like this, please do fill it in. We do take it seriously, most MV wishes get read by an engineer within an hour of them being made.
