Vikings season 5 volume 2 region A availability?

[Nakanokalronin]

Sorry I'm new here and don't know where this question should go. I have all of the Viking seasons on Blu-ray, but it seems Season 5 volume 2 is not available for region A players. Any chance it will become available one day and any explanation on why they made this particular season / volume unavailable to the U.S. market? I'd even buy them on DVD if that's the only way I could obtain it. Physical media is the only way I can watch T.V. since I'm not into paying for multiple subscription services to watch different shows. I feel like I may end up selling all of the other seasons and stop watching the show altogether if I'm going to have a gap in the collection.
