Protecting the video content

Hello,
I just created a paid course for one of my friends and I’m struggling to find a way to protect the video content from being shared.
If I’m embedding unlisted youtube videos for example, the student can easily share the video with non-course members.

Is it a way to add a layer of protection on it? Like disabling the “share” button and make it unclickable with the right mouse button?

Thank you so much for your help
