Use - All users can view price books and add them to opportunities. Users can add any product within that price book to an opportunity.
View Only - All users can view and report on price books but only users with the “Edit” permission on opportunities or users that have been manually granted use access to the price book can add them to opportunities.
No Access - Users can’t see price books or add them to opportunities. "Use this access level in your organization-wide default if you want only selected users to access selected price books". Then, manually share the appropriate price books with the appropriate users.

AC. If OWD for price book is View Only, any user with Edit permission on the Opportunity can add products from the book. So to avoid this behavior, the No Access must be used. The price book will allways need to be manually assigned.
