MAX77958 SNK PDO Set

The datasheet notes that "Default sink PDOs: 5V/3A, 9V/3A, and 15V/3A", and it is noted in another question that to change the default PDOs, we must use the "SNK PDO Set" OpCode. But what I am not sure on is if there is a race condition between the OpCode being triggered and the first PDO being requested.  The OpCode must be triggered by an event, so if I wanted to only support 5V/3A, and 9V/3A Sink PDOs, I suppose the best I could do would be to use the "SNK PDO set" Opcode trigered by "DONE_POR" event.  Would this guarantee that the 15V PDO can't be negotiated? If not, is there a better way to set up the default sink PDOs?
