Hello!
Can you give me more information? Do you mean that you dont want the CDN to activate for a specific URL path? i.e. site.com/your-path , turn CDN off?
If this is the question, unfortunately this is not possible currently with the way the plugin is currently implemented.
You could turn off the CDN plugin and implement your own rewrite rules in your .htaccess file to rewrite any static assets (i.e. images/media, css, js ,etc) to go through the CDN url and then in your rewrite logic you could omit the rewrites for specific paths. If you are experienced in rewrite rules this is the best way to accommodate this request currently.
If enough people ask for this as a feature, we would certainly entertain building it into a future plugin update.
Thanks!
