Have you got a reference for that Dozy? The only thing I'm aware of is EXPedite Mode which is selected by a button on the FCU - however this wouldn't be used in an immediate avoidance scenario. It results in a target speed of GN DOT for EXP CLB or Barbers Pole for EXP DES and aircraft entry into the mode is "positive" i.e. not blended for pax comfort.
