In the Dash, in the app scope, you have a list on lenses. When you click on a lens, you can disable it or enable it. Disabled scopes should be greyed out. And they are, but only after a reboot (or maybe a log out), so there is no immediate visual hint that one particular lens is disabled. It is still the case in Ubuntu 15.10 64bits.
