How to disable shortcut to launch (Samsung's) S Voice *without* accepting its ToS?

By default, when you double-tap the home key, you'll launch straight into S Voice.

To disable that shortcut, one could

load S Voice, then press the menu key and hit "Settings." Next, uncheck "Open via the home key." That's it -- with the shortcut combo disabled, the home button should respond immediately as opposed to with a very slight delay.

However, this method seems viable only once Samsung's Terms of Service (ToS) have been accepted - only after which S Voice will launch fully. Any way to disable that key combo without having to accept ToS of a S I do not want?

_{Note that at this stage I do not (yet) want to uninstall S Voice. If you happen to know how to uninstall it, I'd appreciate a comment, though :-)}
