That will remove the login form and remove the fields "name","username", "password" of the registration form and no user account will be created for the user.
You'll be able to do it following these instructions with a commercial version of Hikashop, are you sure that you're using an essential version, and not a starter one ?

You'll just have to create and use a shipping method through "
Hikashop->System->Shipping methods"
