You can't, and it wouldn't be a good idea even if you could.

I think what you're really saying is that you are trying to create a
Postgres data directory directly on a filesystem mount point.  Don't do
that (it's a large-caliber foot-gun even aside from permissions issues).
Make a subdirectory in the mount point, and use that as the data
directory, and make sure it has the right ownership and permissions.
