Hello!

You are correct: --no-substitutes should entirely inhibit connections to
the substitute servers.

Commit 151afd84dc9bf8f13de79a689f7f163fba7254ec (May 31st) fixed
something in this area.  However, the change is in ‘guix-daemon’, so you
need to build and install ‘guix-daemon’ to take advantage of it (the
current ‘guix’ package with version 0.10.0-0.e901 is older than this
change.)

HTH,
Ludo’.
