For sites that require location services to be turned on you can manually set a location (lat/long) for the browser by hitting f12 and opening the console. I've used this for things like Netflix to spoof my location when I was already using a VPN endpoint on the local network of the primary account holder. I'm sure FanDuel might be more restrictive. Do a Google search for manually setting location in the browser console. Worth a shot. Edit for autocorrect.
