Disable plugins on certain pages

Hey guys!
A few plugins running on my website make lots of http-requests and I would like to deactivate them on the most of my pages where these plugins are not used.

During my researches I found the Plugin Organizer, which is unfortunately not flexible enough for me because it would take a lot of time until I finish editing hundreds of pages. And I really don’t want to edit every page one more time when I want to change something 🙂

So do someone of you know a better way to disable plugins on pages?

Thank you!
