VPN with RD+ and TPB+

So - I know you don't need/aren't supposed to use a VPN when using RD/Torrentio/Stremio -- I got that.

I do use a VPN for other apps; so I've set up split-tunneling on the firestick, which functionally stays *on* for the other apps and turns off when I use Stremio.

However, I've also read that -- if the only options that pop up are TPB+ (or, anything *other* than RD+) then you *do* need to use your VPN.

How are people doing that? Are you literally manually turning on/off the VPN (because, I don't believe you can split-tunnel based on an add-on to the app; I think it's either ON for the app or OFF for the app).
