You can encrypt files with any of many programs including GPG, then
burn them to disc.

But that ought to be obvious, so I guess you mean encrypting the
whole filesystem with the (unspecified) OS. On Linux LUKS
apparantly works for creating ISOs that can be burned to disc:

Wikipedia says that Windows Subsystem for Linux supports LUKS. I
haven't used WSL myself so I'm not sure how easy that would be to
use.

Or if you mean encrypting a Video DVD for copy protection while it
can still play back on normal DVD players: No, or at least not
where the encryption isn't completely insecure.

Thanks
I need it for DVD players, so I guess no.
