Function to hide "Choose payment method later" on draft orders

I have a store setup to take take draft orders for B2B customers and we want to capture the credit card which isn’t a problem. The issue we get is that another payment method called “Choose payment method later”. I’ve tried a few apps on the shopify app store to see if this is possible before I build it into my app but I cannot seem to hide it.

Is there a limitation in functions where I cannot hide this particular payment type?

I worked it out. Its actually called Deferred. Once I set this to the keyword, it hid " Choose payment method later" as a payment option.
