Is there a way to disable the thresholding (binarization) from command line or Tesseract C++ API?

Hi

I have been trying to figure out if there's a way to disable the default thresholding done by leptonica during pre-preprocessing. I think in some cases when the scan quality of PDFs is good enough, the thresholding step ends up deteriorating the OCR accuracy. I have a feeling that thresholding is not really needed for all cases. The only way I could disable the thresholding step is by commenting out the following lines in baseapi.cpp . Is there any other way?

/*if (!thresholder_->IsBinary()) {
	tesseract_->set_pix_thresholds(thresholder_->GetPixRectThresholds());
	tesseract_->set_pix_grey(thresholder_->GetPixRectGrey());
	} else { */
	tesseract_->set_pix_thresholds(nullptr);
	tesseract_->set_pix_grey(nullptr);
	//}
