4K UltraBox+ binding (ADB NCP-3670SF) - I'm looking for info/docs/exisitng solutions

I’m looking for any info about existing bindings or attempts to make them for 4k UltraBox+ (ADB NCP-3670SF). It’s a set-top box/satellite receiver used by Canal+/NC+ definitely in Poland and most likely in France.

Edit: that might provide some info
I also contacted the manufacturer of the box to provide documentation.
