Can I use Home Assistant to stream content to my Chromecast fetched with a VPN tunnel?

So I can easily watch for example Netflix USA on my Phone or PC through NordVPN, but I can’t seamlessly get it on my TVs. I’ve seen that many solve this by including the VPN in a router, but with a bigger family (got 3 kids) and many devices, it’s a bit cumbersome to change a Chromecast between different networks (it must be reset right?).

Anyway — I was wondering, is there a way to solve this through Home Assistant?

If I understand Chromecast, they just go to designated url and stream the media. Shouldn’t it be possible to obtain the device on one device with VPN and then redirect as a new stream to the Chromecast?
