Honestly speaking, there is no way to help you eliminate Twitch ads completely. You can reduce the frequency and can only allow verified ads to reach you. If you use a VPN, you can easily switch to a location where Twitch is less ad-heavy. Even though a Twitch Turbo subscription claims to provide an add-free version, it will only help you stop the 3rd party ads. The streamer-offered ads will still be there.
