An account setup with Pay by bank will have additional options in the Payment Page:

Default Payment Method Displayed - Choosing a payment method here will set the default during the payment journey. Customers will have a default method already selected for them while making their payment, encouraging one method over the other. The customer can choose the alternative if they wish.

Set Card Limit - Adding a card limit will only allow the Pay by Bank option to be selected if the user sends a payment request above the limit set. This is used mostly when trying to reduce or avoid card processing fees on larger transactions.
