Is it possible to exclude a category from being added to the flat catalog index or index in general? The problem: we have a huge set of data in one category (5mio products). It's only accessible via search (elasticsearch), and not visible on the frontend.
But the rest of the products (about 12k) need to be visible and accessible via URL, when the client adds a new item. So we should have update on saving - but excluding that one big category.
