@j1nk0: Featured Post Slider is created to highlight your post in your slider. So, it’s automatically linked to your post. We generally don’t recommend to remove the link. But if you need to remove the link, then you need to build child theme and edit it. As if you edit directly is core theme file, all your edits will be reverted back when you update/upgrade your theme. For more about child theme check out http://catchthemes.com/blog/create-child-theme-wordpress/
Then after you create your child theme, you need to copy the function catcheverest_post_sliders() in your child theme functions.php file from Catch Everest theme catcheverest-fucntions.php file. Then remove the links.
OR the easiest option is to Upgrade to Pro version and then you will get option to use Featured Image Slider, where link is optional. See this for more details about Featured Image Slider http://catchthemes.com/blog/videos-blog/video-series-adding-featured-image-slider/
