How to hide billing address in paypal pro form

How to hide billing address fields in the paypal pro form for selling digital goods?. Thanks.

Why do you want to hide it? With the world’s governments all moving to get gateways to collect taxes on their behalf you are going to need the billing address to know how they need to be taxed.

I also expect that PayPal needs this info to complete a credit card transaction where the user is not a PayPal customer.
