Yes. You have a few options here!
You can download Raven Desktop at Raven.com/Desktop, make sure that you turn off AI OCR in settings, and scan to a local folder. However, your documents will not be searchable PDFs after you turn AI OCR off.
Additionally, if you have TWAIN compatible software that only applies OCR on its end locally, then you can scan directly to that program without the document passing through the cloud.
