If radio-altimeter is set to 100m (10:10:07,2; 10:10:10,6) and flying in auto-pilot mode (FMS, Universal Avionics UNS-1D), can it go below 100m without switching to manual mode?

I think that it has not been published that AP had been controlled by FMS. I read that vertical canal AP was switched in pitch stabilisation mode, setting only by nose down/up button. In this case there is no linking to altimeters.
