How to block users from using Schedule Installation option after software updates

[cmnd_ctrl]

After pushing updates to the client machines the users are prompted with the restart now message. Many users are not restarting now and put it off for many days and clicking on Schedule Installation in which the configuration manager properties box comes up and under the Updates tab they are checking the box for Install required updates on a schedule and setting their own Recurrence pattern. I need to know how to lock this down so they don't have the option to click on Schedule Installation and I don't want them to know to be able to go into the Configuration Manager Properties box to mess things up and keep putting the restart off to future dates. This is a big problem that I need help in locking down.
