Deleting css Visual Composer

Hello everybody, I am wasting a long time looking for how I can deactivate 3 css about js_composer plugin.

I would like to have only 1 css with all classes includes (to improve seo), I’ve got it, I found how I can delete these stylesheets with function.php and others searching inside the plugin code.

But now this 3 css lasted and I don’t know what can I do:
./wp-content/plugins/js_composer/assets/lib/owl-carousel2-dist/assets/owl.carousel.css
./wp-content/plugins/js_composer/assets/lib/owl-carousel2-dist/assets/owl.theme.default.css
./wp-content/plugins/js_composer/assets/lib/animate-css/animate.css

Does anybody know what can I do?

Can anybody help me? Thanks!!
