Remove "Review" Option from Events

I searched the forum and have the following:

In functions.php:

function default_comments_off( $data, $postarr ) {
if( $data[‘post_type’] == ‘gd_event’) {
if( !($postarr[‘ID’]) ){
$data[‘comment_status’] = 0; //0 = false | 1 = true
}
}
return $data;
}
add_filter( ‘wp_insert_post_data’, ‘default_comments_off’, ”, 2);

In Style.css:

.gd-post-gd_event .geodir-rating, .gd-post-gd_event .geodir-pcomments {
display: none !important;
}

But, the reviews tab still appears within the event listing. Is there a child-theme setting I can use to overwrite/remove that tab? or do I have to edit the events plugin itself? thanks!
