Show meta box only when post is being published first time

I haven’t tested this but the idea is to check the post status, if the post is not published, show the metabox otherwise don’t.

function non_publish_metaboxes() {
    global $post;

    if(!isset($post))
        return;

    if($post->post_status !== 'publish'){
        // ... Show Metabox
    }
}
add_action( 'add_meta_boxes', 'non_publish_metaboxes' );
