How to remove an input in form created billing-address.html by ko in Magento 2

Question

I have to remove fax input from billing-address in checkout process. ( when you check out "My billing and shipping address are the same" and the form appears )

Found that is generated here :

Magento > Checkout > view > frontend > web > template > billing-address.html

<!-- ko template: 'Magento_Checkout/billing-address/form' --><!-- /ko -->

No idea where those inputs are generated, i only want to remove fax from there, allready tried to remove fax from checkout_index_index.xml layout with no luck. I dont understand how "ko" works or where i can change this.
