Early reports on this unit indicated the horizon can be disabled.
Don't know the means or whether such disabling would be considered
equivalent to having a conventional mechanical gyro instrument removed
from the glider. *It seems the designers did consider the need though.

It will remain to be seen as to how it is disabled and how this is
confirmed so enforcement isn't a PITA.
