Total plugin deactivation.

Greetings, I have two plugins, WooCommerce UPS Shipping and WooCommerce USPS Shipping. Each time a product is added to our side cart the plugins perform calculations. The more items that get added to the cart the longer the calculations thus slowing down the time it takes to get items in the cart. This is not desired. The same thing happens in reverse while deleting items from the side cart.

When I disable both plugins on the plugins page ( /wp-admin/plugins.php ) the add to cart operation and the delete items operation is super fast

I only need the plugins to be active on the checkout page so I have attempted to disable the plugins across the entire site excluding the checkout page using these methods,
CUSTOM URLS >> PLUGINS BY URL , FRONT END URLS
POST TYPES
SINGLES

After doing this with FDP nothing changed, the add to cart and delete from cart are still allowing the calculations to take place in the side cart.

It is only when I deactivate the plugins on the wp plugins page do I get the add to cart and delete from cart speed boost.

What else can I do to get the two plugins totally deactivated on all pages except the checkout page?
