Unfortunately as far as I know there is no standard PGN for that. Manufacturers may have proprietary messages for that. If you know your displays can do that, you can spy network and try to resolve, which PGN and field will be used for changing. For spying it is best to separate all other devices from network.
Which PGN should be used to send an Illumination or back-light control to all displays configured to receive this setting from the network?
