Possible to set specific DNS or VPN for Netflix only?

I've been scouting round looking for solutions that mean (as an expat) I can continue to use a DNS or VPN service for most things (UK TV, amazon prime etc.) while still retaining access to Netflix. No joy so far. What I'm wondering is if anybody has a way to set a specific DNS (or VPN if that works) for Netflix services, while using the default on the router for everything else?

A bit optimistic probably, but thought I'd ask ...
