Deactivate the controller "Activate Now". Once you disable this setting, the icon will disappear in the status bar. You may also need to deactivate the "Enable as planned" option by using the slider, as long as you have stored a time at which this mode should be active.

You now know why the circle with the dash in the middle appears in the status bar of your Samsung Galaxy S7 and what it stands for.
