Found out how to do this (2025, Australian eBay).

- You need to first go to your payment policies (My eBay - Account - Selling - Business Policies)  and make sure you have one that does NOT have "require immediate payment.." , or create a new one that does.

- You can then Bulk Edit - Payment preferences -Business Policies - and choose the Payment Policy - select Change to " and choose the new policy that does not have immediate payment associated with it.  Don't forget to press save.
