The former French international returned to the starting eleven for the first time since the middle of December to put in a commanding display alongside captain Scott Dann at the heart of the Rovers defence.
Jordan Rhodes put the home side in front after 37 minutes but Rovers couldn't grab that all-important second goal, but the defenders, and Givet in particular, were where they needed to be when it counted to ensure a second clean sheet, and a second win in successive games.
"He was awesome, absolutely awesome, it was a phenomenal performance," said the Rovers manager.
"He's a warrior of the highest order. I can't thank him enough, massive respect to him for that level of performance.
"I think it inspired everybody else. His experience proved invaluable.
"The crowd appreciated him and I think that went both ways.
"The club is blessed with three outstanding centre halves in Grant Hanley, Scott Dann and Gael Givet and Gael has shown his worth there."
