Does scanning with CARE Dose 4D lead to a change of HU values?

The HU values don’t change whether CARE Dose 4D is switched on
or not.
A change in the tube voltage can lead to different HU values, but the tube voltage is not affected by using CARE Dose 4D.
It is only the number of quanta (= the mAs value) that will be adapted by CARE Dose 4D.
