RS CLI -- how can i get lens distortion info into colmap or radiance field registrations?

Hello

Im trying to tune my headless photogrammetry pipeline and would like to export the lens distortion information to Lichtfeld Studio. I cant figure out how to get the cameras to be anything but pinhole. If i open the rs file in the gui and select an image i can see that it has its registration lens distortion set to Brown 3.

There doesnt seem to be any actual distortion settings in the registration apart from making undistorted images.

here are the settings i use:
realityscan-cli -headless -printProgress -newScene -addFolder [my folder] -selectAllImages -setPriorCalibrationGroup 0 -setPriorLensGroup 0 -editInputSelection “inpDistortion=0” -editInputSelection “inpDistortionModel=2” -deselectAllImages -align -selectMaximalComponent -exportRegistration “$5\transforms.json” “$6\transforms2.xml” -quit

is it possible?
thanks
