I was curious about this so I looked around a bit. My interpretation is that GrapheneOS still has not cracked this nut. Neither has iPhone, unless you enable "Lockdown Mode"

4G only, 4G+5G only and 5G only mode has been a thing on GOS for over a year.

5G-SA only is a separate issue which currently neither devices support.
