Tacx NEO Bike Smart 1 by shifting ?

Hello!

There are several shifting options such as triple and three variants of double, but since I only ride bikes with 1 by shifting: Why is there no option for 1 by shifting with the Tacx NEO Bike Smart? It's just software, right?
I would like to configure the 1 by Shimano GRX with, for example, 40t/10-51t.
No one rides with triple gears anymore, and even double gears are really annoying for me, as I'm only used to 1 by shifting ;-)
