Not yet. It appears that BMW has disabled the ability to change display units from the TFT instrument cluster itself for all USA-spec bikes. Non US-spec bikes are able to change the display units through their handlebar controls in the bike menu of the instrument cluster and we have confirmed this on our in-house R1250GSA. These changes are done within the instrument cluster's  internal memory and overrides any ECU coding changes. As such, we are investigating the ability to enable and disable this functionality through ECU coding in future versions of the GS-911 software.
