The camera is factory calibrated and for many purposes this calibration should be good enough. If you really want to, you could calibrate both IR cams as described in StereoCalibration, however.
It's now one year later...
Have you found a solution? :)
I faced the following problem when trying to run the StereoCalibration. It seems the calibration only accept color images.
kuxz@kuxz-UX32LN:~$ rosrun camera_calibration cameracalibrator.py --size 9x6 --square 0.108 image:=/camera/ir2/image_raw camera:=/camera/ir2 --no-service-check

Is there any parameters that I can edit to enable the calibration of the IR camera?

The driver already gives you a depth image, wouldn't it be better just to convert the pointcloud to a disparity image?
