By placing this Code in the header as a custom code, it will hide the scrollbar. Worked properly on my end.
<script>
window.onload = function() {
var style = document.createElement('style');
style.type = 'text/css';
style.innerHTML = 'html { overflow: -moz-scrollbars-none; } html::-webkit-scrollbar { width: 0 !important }';
document.head.appendChild(style);
};
</script>
