Remove product without price from shortcode recent products

Hello,

I have the following snippet in use

add_action( 'woocommerce_product_query', 'react2wp_hide_products_without_price' );
function react2wp_hide_products_without_price( $q ){
   $meta_query = $q->get( 'meta_query' );
   $meta_query[] = array(
      'key'       => '_price',
      'value'     => '',
      'compare'   => '!='
   );
   $q->set( 'meta_query', $meta_query );
}

With this snippet I hide the product with no price from my shop page.

Is it also possible to have a snippet like this but then for the woocommerce shortcode recent_products?

Because I use this shortcode on my page:
[recent_products per_page=”6″ columns=”6″ orderby=”date” order=”desc”]

And in this shortcode the product without any price are shown and I also want to hide these products without any price from the woocommerce shortcode.
