Problem:
How to disable specific products for a specific language?

Solution:
The way to exclude products from specific languages is to simply not translate them.

Important is that you do not display the original content, as long a translation does not exist (fallback) which means you need to make sure to set WPML -> Settings -> Post Type Translation -> Products to "Translatable - only show translated items".

Another way, in case the products are already translated, would be to go to the products list and set those specific products as "Draft" or "Private", which will make them only visible to admin users.
