nginx-upload-module

I would love to use NGINX's upload module that takes care of writing files to disk from form submissions.
It looks like NGINX after writing the file then forwards the filename to the backend instead and the file form field amongst others are removed but you can configure which fields to forward to php.
Can the default file field take a path name for the file instead of the forms base64 out of the box?

Thank you.
