Hello,

We are glad that one of your issues has been Resolved.

1) Sorry but there is no option in Theme Settings available to disable the scroll.

2) Please try adding the following Code in the Document Ready Custom JS in the Custom JS area under Theme Settings >> Custom JS.

setTimeout(function() {
    var $tabs = jQuery( '.wc-tabs, ul.tabs' ).first();
    $tabs.parent().find('#tab-description').hide();
    $tabs.parent().find( '.tab-title-description' ).removeClass('active');
}, 1000);

Best Regards
