How to hide products in opencart?

Question

opencart

Tell me how to hide products in ocStore 2.1.0.2.1 with a remainder of -100 (do not delete them) without reference to the status, just hide products with a remainder of -100)
I found such a solution, but it does not work for me

In the file catalog/model/ catalog/product.php

About line 78, find:

$sql .= " LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) WHERE pd.language_id = '" . (int)$this->config->get('config_language_id') . "' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "'";
Replaced by

$sql .= " LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) WHERE pd.language_id = '" . (int)$this->config->get('config_language_id') . "' AND p.status = '1' AND p.quantity > 0 AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "'";
