I bought an android box rebranded by my satellite TV provider. It's got Amlogic S905X2 so it should support Dolby Vision. There is even an option for Dolby Vision in advanced options but it's greyed out. I guess my provider didn't want to pay for the licence or something. Is it possible to somehow bypass these options?

It's hard to say exactly which model I have but it's similar to Skyworth Binge Android TV box except mine supports Netflix and has 16GB of built-in memory.
