Found this to work really well for a WordPress custom theme where the only option I had was to drop an override via a header/footer plugin option:
<script> var ref= window.location.pathname; var search="/youruniquepagelink/"; if (ref.indexOf(search) > -1) { let myElements = document.querySelectorAll(".your-class"); for (let i = 0; i < myElements.length; i++) { myElements[i].style.display = "none"; } } </script>
