Unfortunately not, as the problems comes from the underlying OSM data.
It is a peculiarity of German city counties ("kreisfreie Städte") that
they are only mapped once with their lowest administrative level in OSM,
which is county (or even state for the three city states).
There is no way for Nominatim to know that those counties also
represent a city.
