Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+

This tool does require command line access to run, so there’s a bit of a technical hurdle for some, but it’s overall straight forward. You’ll copy over the existing settings from your usb/sd card installation so is a transparent move.

While preferred for my needs, I couldn’t get single-boot install to work. Dual-boot seems just fine, though, if you run into any issues.
