IPVanishVPN also has split tunneling
Torguard also has split tunneling
torguard
PIA?
Any VPN that supports OpenVPN, as the OpenVPN client has that feature (whitelist/blacklist).
I use this combination and it works perfect for me :
Device : Amazon firestick
App : Smarters IPTV
VPN : Nord VPN
IPTV PROVIDER : CLOUDSPAL HOSTING
Digibit and they're cheap
proton vpn, ip vanish and nord all have spilt tunneling
PureVPN has it and works great
ExpressVPN app in FireTV allows you to do that perfectly.
