Hi,
I am sorry, I mixed up two questions.
I was already one thought ahead.

1. Question about activating all profiles at login time
2. Question updating all profiles at once.

1.
to avtivate all profiles at once
You wrote that it would be better to have only one package in one profil.
So I would have to use each package in a separate profil

Musescore version 4.0.2
and Musescore version 3.6.2
are in different profiles,
so I guess it shouldn’t be a problem
What do you say?

2.
To update all profiles at once
this is a different question, which I have to deal as well.

Is there a way to do it?

Is there a way to exclude the profile "Musik" because this profile I
  have to upgrade with:

  guix package -p /home/gfp/Projekte/Musik/guix-profil -m
  /home/gfp/Projekte/Musik/musik.scm

  or put Musescore 3.6.2 in a separate profil,
but still the question remains, that this profil should then not be 
included in the update process.

  Kind regards

Gottfried
