I suspect FlightDetent has it..
In the event of thinking a smoke/Fire warning is credible and most especially if you consider it may be uncontrollable you need to get the airframe on the ground as soon as possible...(checklist usually says that somewhere, often first item after diagnosis complete).
it's not a case of "to busy to bother" with fuel dumping as much it's low down the list of priorities and given typical dump rates you are not going to reduce weight significantly in the time available if you are aiming for an expeditious landing.
