On your website, you can include a custom form for customers to enter their shipping address before you direct them to the Chargebee checkout page.
If you're using the V2 checkout pages, based on the customer's shipping country, you can then pass the addon to the hosted page URL as a parameter.
Similarly, for V3 checkout pages, you can then pass the addon script to your application using the "product.addAddon(addon: Addon | string)" as shown in "Add-on customizations" example in this doc.
