Set member names visible only by owner and administrator

Hi,

I have few projects, members have to register to git clone (and more depending of their project access), but all of them for now can see the project members name.
actually it seems that even public can see the names of the project members.

I’ld like the keep the member’s name private, only the owner of the git, (or the owner and the administrator) should be able to see the member names in my case.

is it possible to do that ? how ?

Regards
