How do I make my featured image in my blog post unclickable?

Hello,

I'm trying to create a testimonial section on my home page with images and text that you can click through in a gallery carousel. I figured out how to do that but I want to make it so that my featured image is not clickable. (scroll to the bottom of my home page to see where I mean). Right now the image is linked to a blog section that I don't want visitors to be able to see. Is there a way to do this? If not, how else can I display my testimonials with corresponding images in a click-through gallery like this? 

This appears to be a summary block. You can use this code in custom css. If you have other summary blocks you don't want to change then put this code in a code block on a single page with <style> at each end. 

  .summary-thumbnail-container { pointer-events: none !important; }
