NBD server and client

Possible this is already asked, but a search didn't find a result.

Is it possible to set libreelec as a nbd-client to access a nbd server, so it is possible to acces a dvd-rom over the network. And if yes, can it be binded to the pop-up "play DVD" on the homescreen (I'm still on Confluence) as when you insert a dvd in a native dvd-rom? In general can you configure the "play DVD" pop-up?

Don't bother, I just logged in with ssh and see nbd-client is there. So it should be possible to mount a dvd over the network. Now I have to check if confluence picks it up as a cd-rom. Maybe if I map the device to /dev/sr0.
