Hi,
There is no such option for the moment in HikaMarket but I don't know if it could be useful.
If the stock quantity of a product is "0", the customer can't add the product in their cart. It has globally the same effect.
If you want that the vendor automatically have "no stock" products, you can use a specific "product template" for the vendor and configure this template with a "stock quantity" set to "0".
At this moment, when the vendor will create a product in your store, the stock quantity will be set to "0" and the customer won't be able to add the products in their cart.
