Q = Is it safe remove all that packs?
especially anaconda, NetworkManager-team ?

Yes, anaconda is the installer. Once you’ve installed your system, you can safely remove it.

The rest should be OK too. DNF is telling us that they are “unused dependencies”, i.e., they are not used by any other package in your system. If you need them later, you can always reinstall them.

You can check what these packages do yourself to be sure too:

$ sudo dnf info NetworkManager-team
