Adding Freesync to unsupported display

Been doing the big think. I have an lg 43ud79-b display and early reviews mention freesync support. Well I’ve had it for about a year and even the latest firmware doesn’t enable support. Would it be possible to either A) purchase a new controller board for the panel that supports freesync or preferably B) Add support via modded controller firmware? The display is fantastic but it lacks this one thing I’d really like to play with
