Unfortunately there’s no option in Jupiter to disable responsiveness of the website. Because many things are chained together. And it’s bad practice too. Because nowadays search engines consider responsiveness of the site a positive point.
However you can fine-tune different aspects of the site on mobile if there’s anything wrong.
The good news is that you can even display a whole other slideshow on mobile and hide the desktop version.
Having the desktop version on mobile is not a good idea as well, since the navigation gets hard and everything becomes so tiny.
So that is my suggestion to fine-tune the mobile version.
