Hi photogenic ,
Unfortunately ATUM doesn’t support actually third party plugins that add new product types to WC (except WC Bookings and Subscriptions). We're planning to add support to several product types at a later stage.
However you can try using the filters included in the Globals class “atum/allowed_product_types”, “atum/allowed_inheritable_product_types”, “atum/allowed_child_product_types” and “atum/product_types_with_stock” if you are comfortable with the code.
Hope this helps.
