I am looking for a FTP Server app that can just run automatically every time the Android TV device turns on. Does anyone know of one that can do this?

I currently have ES File-Xplorer but I have to manually turn the FTP features on. Looking for something that will just run automatically at boot and turn the FTP server on.

I am running a NVIDIA Shield as well as a few Amazon Firestick 4k's. Any heelp/suggestions appreciated.
