opencv pca Is it possible to change the reference point(center point) when extracting eigenvectors? I don't want to center point

In the opencv pca function, can I extract the eigenvector by grabbing the starting point I want, not based on the center point? For example min (x, y) point in 2d coordinates.

I want the reference point to be min(x, y) or max(x, y) of the data.
