Default Attribute

Hi,
I want to choose a random default attribute during the bulk product upload phase or in normal situations.
There is such a resource, but it does not seem to be very efficient. Because it does a database query every time a page loads.
Is there any other way to this?

add_action('woocommerce_before_single_product_summary', 'quadlayers_product_default_attributes');
function quadlayers_product_default_attributes() {
      global $product;
      if (!count($default_attributes = get_post_meta($product->get_id(), '_default_attributes'))) {
        $new_defaults = array();
        $product_attributes = $product->get_attributes();
        if (count($product_attributes)) {
          foreach ($product_attributes as $key => $attributes) {
            $values ??= explode(',', $product->get_attribute($key));
            if (isset($values[0]) && !isset($default_attributes[$key])) {
              $new_defaults[$key] = sanitize_key($values[0]);
            }
          }
          update_post_meta($product->get_id(), '_default_attributes', $new_defaults);
        }
      }
    }

Also, for products with variations, is there a way to initialize the global Attribute %d to 1 for each row during the batch product upload phase?
