Stop Books Invoice From being Sent to customer when Offline Payment Selected in Commerce

Stop Books Invoice From being Sent to customer when Offline Payment Selected in Commerce

I have orders coming in from Commerce, we have an offline payment available on commerce for customers with card on file. (We will change them manually)

When Flow confirms the order, books creates an Invoice and sends it to the customer. 

I need to block the invoice from being sent or we risk double charging a customer.

Can I drop a decision in my flow, or something from automation on books to do this?
