Add to cart if out of stock

Hi
great plugin
On our site you can buy out of stock products as they are branded as a backorder
Unfortunately, only products in stock can be placed in the shopping cart with your plugin
is it possible to bypass this restriction?
I tried to make this change to the listing-list.php file (line 19)

if (isset ($ products) && count ($ products)> 0) {
becomes
if (isset ($ products) {
but it had no effect

how can I do?
THANK YOU`
