I have a Upsell product with a discount.
it should only work like when they buy product A they get Discount on Product B.
But later in shopping cart customer is able to update the quantity of the Discounted Product, this is not correct.

So i would like to disable the update quantity for the upsell product in cart page or remove the update quantity option in the shopping cart completely.

if any one got to implement this, please share your work here.

thanks
