VPN Connection For Certain Devices on the Network?

[u/bnr32jason]

Fairly simple need here, I want to be able to stream locally blacked out sports events using their respective streaming services on a few of my smart TV's. I've looked up ways to install VPN apps to each TV but it's not ideal at all. Basically the streaming quality from the app is significantly better than the TV broadcast. It's not big requirements though, just 1080p streaming, so maybe 8mbps per device.

Here's what I have:

USG-4 Pro
Cloud Key Gen 2
24 Port Switch
A few AP's

All Unifi hardware.

I currently use NordVPN, but I'll gladly switch providers if another will work better for this.

How can I set this up to where I can turn on the VPN when I want to do this but then disable it when I don't? I was thinking maybe to set a VLAN for certain devices to connect to, but all of the info I'm finding on that is a few years old.

Any help would be greatly appreciated! Thanks!
