But the measurement system - that of the NANOVNA - is always in a 50-ohm

Yes NanoVNA 50Om system, but possible use math to see how this DUT measured in different impedance system
For this S parameters converts to Z (DUT impedance constant and not depend from measured device) and after convert back to virtual Z` measured system impedance. This process named impedance renormalization.
As result measured DUT impedance not change, but S parameters transform
