How can I disable automatic order sending to Printful after payment?

Hi. Who has experience with Printful ?

When a customer has paid for an order, that order is sent to Printful.

And this is a good thing. But I need to disable this sending for some products after purchase, because they will have a different design and they will be sent separately to Printful.

The question is how to cancel sending the order to printful after payment or here can I configure this functionality?
