Hide file extensions from native search

I've got a bit of a catch-22 here. Client wants to remove asset image extensions (pear.jpg etc) from appearing in dedicated search - client also does not want the assets renamed to anything other than what the item is. Is there any way I can block the text or remove the entire description from the search? I'm pulling my hair out here.

Try this code to Website Tools (under Not Linked) > Code Injection > Footer

<!-- Remove jpg in search page -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
<script>
const attrObserver = new MutationObserver((mutations) => {
  mutations.forEach((mu) => {
    if (mu.type !== "attributes" && mu.attributeName !== "class") return;
    trimEXT();
  });
});

const ELS_test = document.querySelectorAll(".search-results");
ELS_test.forEach((el) => attrObserver.observe(el, { attributes: true }));

function trimEXT() {
  $(".search-results img").ready(function () {
    $(".sqs-search-page .sqs-title").html(function () {
      return $(this).html().replace(".jpg", "").replace(".png", "").replace(".jpeg", "");
    });
  });
}

$(document).ready(function () {
  trimEXT();
});
</script>

No dice, unfortunately. I appreciate the response, though.
