Accessing the "DreamColor Full Gamut" display primaries GUI option via the API?

Does anyone know if there’s a quick means of setting the “DreamColor Full Gamut” option, the one under your monitor type and then under “Primaries” in the RV GUI, using the Python API?

I know how to set monitor transfer function, but I’ve got a situation where it would be best to also just automatically hit “DreamColor Full Gamut” for a specific monitor in my facility.

Exporting an RV session and checking the source didn’t reveal any immediately-apparent ways of just getting that setting dialed in. Thanks for any help anyone could provide!
