These parameters are hardcoded. You can find them in modules/calib3d/src/fundam.cpp

I won't discuss why they are hardcoded - just that for 99% of situations the defaults are best.
If you want more control over your homography, use cv::findFundamentalMat() - you can specify the algorithm and its parameters in great detail.
And if you still don't like it, fork OpenCV and tune it yo your needs.
