This snippet checks the cart contents and will remove the billing fields if there are only virtual products in the order.
This means your customers will only need to enter their first name, last name, email address, and optionally any order notes.
If you wish to remove Order notes you can view the guide here: How to remove the Order Notes section from the WooCommerce checkout.
Keep in mind, some payment gateways require billing fields, particularly the postcode, to process orders.
