Welcome to the forums. You can switch them off with the toggle at the top right of the screen. This will reset any changes you did and restore the default values. If you want them to disappear from your settings screen list, you need to clear data for the settings app (settings - apps - all - settings). This process will remove all your personal changes in the settings and restore to the original values. Too much work, I guess. And even so, in some phones only a factory reset will do the trick. Not worthy my opinion.
