Clean remove of Plugin Supporter. How to?

Hi Team,

I want to remove the Supporter Plugin.
What is the best way for a clean and complete De-Installation?

Supporter is not needed at the moment, maybe(!) in a couple of month we come back to use that Plugin. Right now, Membership is the Plugin we need and want to use. Both Plugins are installed right now, and i want to remove the Supporter.

PS: the Site is up but not live. So there are no subscriptions to take care of...

Thanks in advance,
Rainer.
