How to add YouTube as a service
Only your domain administrator can enable YouTube on your domain. Let the domain administrator know you'd like them to turn on the ability to add YouTube as a service. Once they've done this, you should be able to add a YouTube channel directly to G Suite.
If you're the domain administrator, find out how to add services to your G Suite domain.
