How do I install DRM into Android TV

I was using Tubi for awhile and I realized recently that the reason only some shows can play is because those shows don’t require DRM. From what I read, DRM is a program you can install into Android. Where can I get a program to install to allow DRM?

It’s not, it’s a set of libs that comes with your Android distro

Try some other, you are running a custom one right?

I am running LineageOS ATV. I am just looking for a custom ATV ROM or some custum ROM that gives an ATV like experience.
