If certain skills aren't suitable for your channel or you don't want them enabled, you can disable them via your Mixer Broadcast Dashboard.
To get started, head on over to the dashboard by using the following link: https://mixer.com/dashboard
Once there select "Skills" on the left hand menu.
You'll be presented with a list of Global and (if enabled) Channel Skills:
To disable a skill from being used on your channel simple click the toggle for that skill to toggle it off.
Disabling a Skill may take a while to come into effect, so we recommend that you configure your skill preferences before going live on Mixer.
