I must say, none of that makes any sense to me.
I just installed a new VM using Fedora-KDE-Live-x86_64-30-1.2.iso. Even the
live image has /etc/nsswitch.conf as a sym link
to /etc/authselect/nsswitch.conf
And when I connect with that newly installed VM, without having done any
updates, I see.
[egreshko@f30k ~]$ ll /etc/nsswitch.conf
lrwxrwxrwx. 1 root root 29 Jul 19 06:25 /etc/nsswitch.conf ->
/etc/authselect/nsswitch.conf
and
[egreshko@f30k ~]$ ls /etc/authselect/
authselect.conf dconf-locks password-auth system-auth
custom fingerprint-auth postlogin user-nsswitch.conf
dconf-db nsswitch.conf smartcard-auth
So, it is hard for me to understand how your results could be so different
than mine unless you've then made changes to your
system out of habit.
Maybe you can double check what version of fedora you actually did install
at the start? Assuming the logs haven't been
overgrown you can do "dnf history info 1'.

That's what it says.
Doing some more poking:
/etc/nsswitch.conf is owned by the glibc package, according to rpm.
rpm -q -l -v glibc says that it's a plain file. It is not a symlink.
I'm going to guess that it's authselect that replaces /etc/nsswitch.conf
with a symlink:
# authselect current
No existing configuration detected.
I also note:
[root@thinkpad ~]# authselect test minimal
File /etc/nsswitch.conf:
# If you want to make changes to nsswitch.conf please modify
# /etc/authselect/user-nsswitch.conf and run 'authselect apply-changes'.
#
[ more stuff ]
That sounds more like what you are seeing on your machine.
