unfortunately, no , not out of the box. FTP is File transfer protocol, and it does just that. How ever you can implement it in software if you want similarly to how firmware update works. Write a code that detects if uploaded via ftp file name is new_settings.txt (for example), then read it and apply new settings programaticaly. This way every time you need a change you will be uploading a new_settings.txt file via ftp and your code will process it.
