Withdrawal of price types for wholesalers on the Beatrix website

We have a bitrix editorial business and we want to implement a separate office for wholesalers with their own price. But we ran into a problem during the setup - we cant hide the basic price type for the new group of "Wholesale Users" users, because they fall into the "All Users" group by default. That is, we need to do as I understand the condition in the code to check whether the user is in the group "Wholesale Buyers" or not and, depending on this, deduce the basic type of price.
