@Paul_Mossip Wonderful! Thanks for helping me, I was indeed able to do it my way, It may not be the most optimal way but it works.
I used this video to guide me in the creation of another tunnel.
@Rokas_Musteikis Shared in another post the following domains for Twitch:
ext-twitch.tv
jtvnw.net
live-video.net
ttvnw.net
twitch.tv
twitchcdn.net
twitchsvc.net
So I created an outbound policy rule for earch domain to redirect traffic to the Non smoothing + FEC tunnel and it works perfectly.
Wohoo
