Magento 2: Not Allow to Rest Estimate Shipping and Tax value on qty change in checkout/cart/ page

Question

After Adding a product into the cart I go to checkout cart page and fill the Estimate Shipping and Tax data it is set fine. after that I refresh the page and again check Estimate Shipping and Tax data it is same as which is I set.

Now I Change the Qty of that product in the cart and hit the update button after page load successfully again, I check Estimate Shipping and Tax from data which is reset.

So how to prevent rest Estimate Shipping and Tax from data on Qty update.

                 /* Minicart reloading */
                customerData.reload(sections, true);

                processors.default =  defaultProcessor;
                processors['customer-address'] = customerAddressProcessor;

                var type = quote.shippingAddress().getType();

                if (processors[type]) {
                    processors[type].getRates(quote.shippingAddress());
                } else {
