How to remove Payment Address or Billing address (Step 2) from Checkout process in Opencart v. 3.0.2.0

I am looking to remove Payment Address or Billing address (Step 2) from Checkout process in Opencart v. 3.0.2.0.

I found tutorials for previous version of Opencart (v.2.0), but files are different: for v.2.0 - .tpl for v.3.0.2 - .twig

I'll be grateful for your help
