Hi,

Add the below snippet inside your functions.php file

function filter_grouped_products( $query ) {
  if ( !is_admin() && is_shop() && $query->is_main_query() ) {
    $query->set('post_type', 'product');
    $product_type = array(
      'taxonomy' => 'product_type',
      'field' => 'slug',
      'terms' => 'grouped'
    );
    $query->set('tax_query', array($product_type) );
  }
}
add_action('pre_get_posts', 'filter_grouped_products');

Regards
