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>
