How do I remove the product thumbnail link from a specific div in Woocommerce? [closed]

Yes you can for example target the link itself inside the trending id with CSS and remove the action with CSS itself, in your place it would be something like this:

#trending > li.product > a {

   pointer-events: none;
   cursor: default;

}

Note that this is CSS scheme, not exact CSS, that deppends on classes you have (I would be more specific if you provided link). But the point is you are targeting <li> inside #trending id and link inside <li> itself and you are disabling any events, so that will do the job.

I hope this helps.
