You can;t turn it off completely without disabling all automounting, as I
understand it.
You can do it as a one-shot by using "diskutil list" to see what device
(diskN) the DVD is (this is dynamic and will depend on what other fixed and
removable media is mounted) and then "diskutil unmint diskN" to unmount it;
the automount stuff will then ignore the drive until you are done with it
and either "diskutil mount" or "diskutil eject" it.

Why does Finder own it?

Automounting, primarily. Opening Finder windows when you insert a CD or DVD.

Uses OS X services to release the drive, as I mentioned earlier.
