Samsung Smart TV VPN

Can anyone tell me if it's in any way possible to use a VPN via my smart tv? I have a Samsung smart tv, and I'd like to watch geo restricted content via my TV, if possible.

For example, if I want to watch something via Kodi. But I know the Kodi app is on the TV itself, so I'm not using a browser to try and go via a VPN.

Similarly, if I want to watch TV channel directly on my TV using a VPN, would this be possible at all also?

I have fiber optic broadband, with the TP-link router, so I'm not assured there's a way to VPN all traffic that goes through the router so that, basically, all devices connected to it are via a VPN?

Any help hugely appreciated.
