Hi MiniMiniMantis,
Believable or not, a plugin usually cannot be switched on/off on the fly; that only works in rare cases when the developer designed it this way. For this plugin, it would significantly increase its code complexity.
To achieve something that comes close to what you are describing, you could add a new plugin that does overrides when a certain condition is met (e.g. a Switch is ON). You probably want to ask a programmer to write such a plugin, but technically, it's possible.
