Show past posts only on post slider module

I have a Beaver Themer Archive page that uses the Posts Slider module to rotate through posts and would like to come up with a workaround to show only past posts in the slider. I have a custom query to show the ‘Events’ post type, but there is no query option for showing past/future/etc.

I found someone wanting to do something similar with upcoming events that tried this:

       $today = date('Ymd');
        'post_type' => 'tour-date',        
        'meta_query' => array(
	        'key'		=> 'event_date',
	        'compare'	=> '>',
	        'value'		=> $today,
        // get posts
        $posts = get_posts($args);

and a filter to start with:

function fl_builder_loop_query_args_filter( $query_args ) {
if ( ‘example-module’ == $query_args[‘settings’]->id ) {
$query_args[‘post_type’] = array( ‘post’, ‘product’ );
return $query_args;
add_filter( ‘fl_builder_loop_query_args’, ‘fl_builder_loop_query_args_filter’ );

But I’m not sure how to use one or the other or both correctly to make it work. thank you for any insight!!
