Show the country where is the customer from in the Billing, not all countries where we sell products

Hello! I want to show, for example, Germany in the Billing address in the Checkout if this client from Germany, I do not want to show all countries where we sell. If that possible?

Hi @dombrovskyi ,

Which plan of Shopify are you using?
