How to disable obligated address fields in Drupal Commerce in checkout? In D8 drupal commerce there is a step after the customer selects checkout.

Left in the screen is de payment information which contains a form with:

Country
Company
First name, Last name
Street address
Postal Code
City


We only want :

Country
First name, Last name


I created a hook_form_alter but retrospection of the form gives me no clue which field I can adjust. 

Also I checked in the profile if there are any options and I could not find them?

Any suggestion
You need to edit the address field on the Customer profile type.
See admin/config/people/profiles/manage/customer/fields/profile.customer.address
In more recent versions of Commerce this can be found under
admin/config/people/profile-types/manage/customer/fields/profile.customer.address
