Force India have lifted the standing team orders preventing Sergio Perez and Esteban Ocon from going wheel-to-wheel in races.
Earlier this year, the Silverstone-based team imposed the racing ban on their warring drivers after a spate of collisions.
"Here and also in Abu Dhabi we are free to race without team orders," Perez confirmed in Brazil.
The Mexican said that he is happy with how the 2017 season went for Force India, who can no longer be beaten to a solid fourth place in the constructors' championship.
"It has been an incredible year," said Perez. "I am very proud of my team."
Perez has earned 92 points this campaign, while teammate Ocon has picked up 83.
