Show WPDiscuz only once on a page (under specific tab)

Hi,

Using Learndash plugin and customized it to show the course sections under different tabs.

Would like WPDiscuz to appear under the Discussion tab only, but currently shows up under each tab (since the sections are technically on same page)

Can you recommend any solution on how I can limit it?

here is a start to the logic but not working yet - attached some screenshots.

if( $tab4 ) {

        if ( comments_open() || get_comments_number() ) :
    comments_template();
endif;
}
