To hide the address fields on the checkout page,
Navigate to Settings >> Configure Chargebee >> Checkout and Self-Serve Portal >> Field configurations(on the left panel).
Now go to the appropriate section(billing/shipping/card address) on this page and un-check the Show option for the fields you'd like to hide.

Note: You can hide the fields and can still populate their values in the background via the checkout page URL. Here’s more on that. If you’re using our APIs to generate the checkout pages,, refer to this link.
