How to route FTP traffic to Ethernet in Windows 10

I transfer files to and from my Nexus 6 with FTP via USB-OTG etheet adapter coected to the phone, as it is the fastest method I've found. My computer and my phone are coected with each other through an Etheet switch.

Currently I have to tu off WiFi on both devices when transferring files since the etheet switch is coected to a WiFi bridge and my computer uses it's inteal WiFi card (which is faster than the WiFi bridge) and all traffic is routed through the WiFi coections. This route becomes [computer > WiFi router > WiFi Bridge > etheet switch > phone] rather than [computer > etheet switch > phone].

How do I route FTP traffic to only use the Etheet coection?
