How can I change the vendor preferred payment type (e.g. from TBD to ACH, or ACH to Card)?

The vendor preferred payment type cannot be modified or changed in the Financial Portal.  The vendor or employee will need to register with the ePayments service provider to receive ePayments, or contact the ePayments service provider to change their payment method.   Please refer to ‘Register for ePayments’ under Miscellaneous section.
