Raikkonen quit Formula One at the end of 2009 and spent two years fulfilling an ambition by competing in the World Rally Championship, albeit with limited success.
That resulted in the 2007 world champion returning to F1 this season, signing up with Lotus in tandem with Romain Grosjean.
Raikkonen, however, recently remarked he would love to take part in his home rally in Finland one more time.
Boullier, though, has confirmed such a possibility is not going to happen.
The Frenchman said: "There was a journalist who asked him if he loves rally – yes. Would you love to do rally again? – yes. Would you love to do your home rally? – yes.
"There was nothing else, but contractually he cannot do it. End of story."
