Archive Loop - Show only children

With Divi Machine offering the heirarchy toggle for custom post types, there should be a way to only display children on a Divi Theme page in the Archive Loop.

Essentially:

$my_query = new WP_Query( array(

'post_type' => 'cpt_name',

'posts_per_page' => 1000,

'post_parent' => $post->ID,

));
