subtotal on email notifications without tax

-- HikaShop version -- : 4.5.1
-- Joomla version -- : 4.1.3.
-- PHP version -- : 8.0
-- Browser(s) name and version -- : Google Chrome

I'd like to see the subtotal price on the confirmation emails without vat.
I have been searching in the templates of the emails system>emails and found in the order notification for example these lines:
'CLASS' => 'subtotal',
'NAME' => JText::_('SUBTOTAL'),
'VALUE' => $currencyHelper->format($subtotal,$data->cart->order_currency_id)
);
}
if(bccomp($data->cart->order_discount_price,0,5) != 0) {
if($config->get('price_with_tax')) {
$t = $currencyHelper->format($data->cart->order_discount_price * -1, $data->cart->order_currency_id);
}else{
$t = $currencyHelper->format(($data->cart->order_discount_price - @$data->cart->order_discount_tax) * -1, $data->cart->order_currency_id);
}

But no matter what I try, the subtotal remains with vat. Can you please help me?
