Is the order recalculated when the save() method is called?

Question

1C-Bitrix

I want to manually assign the total cost of the order (sometimes it may differ from the sum of the items in the order), I use API D7.
I give as an example a code fragment where the cost of the order is assigned:

$orderBx = Sale\Order::loadByAccountNumber(1000);
$myFullPrice = 15000; // для примера
$orderBx->setFieldNoDemand('PRICE', $myFullPrice);
$result = $orderBx->save();

The "Order Amount" parameter, which is equal to the value of $myFullPrice, is not always assigned, but is automatically recalculated based on the sum of all commodity items.
Perhaps there are other methods that indirectly cause the recalculation of the order?

If you need to change the amount of the order, it is best to specify the conditions in the rules
