Like dawnerd said, you can use MakeMKV to decrypt and rip the discs, ideally using a BR drive with an unlocked firmware (I have the Asus drive that MakeMKV ships a firmware for). Really the only annoying part is track identification, as there isn't an equivalent of CDDB for Blurays (or if there is, MakeMKV doesn't integrate it), so you have to identify content yourself. When you do that, make sure you do it in the same way that your media server will identify it. I had quite the issue trying to name my episodes as Plex expects them for things like two parters. And while Plex has "AI" credit identification, it isn't super accurate, and is another db service that should really exist but doesn't.
Just dump the man movie + extras with makemkv and copy to my nas. Hardest part is finding a drive with compatible firmware to flash for uhd support (or just buy one preflashed I guess).
