Fuel consumption settings on an Urban GS

[carbold]

I have a KOSO DL04 instrument cluster, which displays all the hidden functions such as fuel consumption, battery voltage, revs, gears etc.
When I plug the GS-911 I can't find the Cluster Coding menu, which in other bikes allows you to change the units (for example mpg to l/100km). I have attached a screenshot of the Cluster Coding menu for a R1200RT.
Is it that I can't find it, or maybe because being the "detected bike"  an Urban GS it just doesn't provide the Cluster Coding  because the OEM instrument cluster doesn't have the fuel consumption?
Any workaround? (e.g. selecting a different bike)?
