Javascript event conflict on Wordpress (ET Divi Theme and Buddypress)

I've built a child theme of Divi Theme to use with Buddypress. So far so good, except for a script conflict on commenting buttons.

The theme load a javascript (js/custom.js at 2642:2662) with the following function:

    $( 'a[href*=#]:not([href=#])' ).click( function() {
        if ( $(this).closest( '.woocommerce-tabs' ).length && $(this).closest( '.tabs' ).length ) {
            return false;
        }

        if ( location.pathname.replace( /^\//,'' ) == this.pathname.replace( /^\//,'' ) && location.hostname == this.hostname ) {
            var target = $( this.hash );
            target = target.length ? target : $( '[name=' + this.hash.slice(1) +']' );
            if ( target.length ) {
                et_pb_smooth_scroll( target, false, 800 );

                if ( ! $( '#main-header' ).hasClass( 'et-fixed-header' ) && $( 'body' ).hasClass( 'et_fixed_nav' ) && $( window ).width() > 980 ) {
                        setTimeout(function(){
                        et_pb_smooth_scroll( target, false, 200);
                    }, 500 );
                }

                return false;
            }
        }
    });

This event target the same button that Buddypress use for commenting, preventing AJAX form from loading on click.

I don't want to edit the parent theme (custom.js). How can I prevent this conflict? Is there a workaround, maybe from functions.php?
