I must admit that I haven't tested the
"never" case for a long time.
I tested this now and the installer correctly respects the setting
"never". So never means never. You don't get any updates nor packages if
you really don't want this.
Configuring LyX seems to do nothing because the "never" option prevents
MiKTeX to install missing packages and thus to update its build system.
However, the "never" settings is for users who know about packages and
how they are handled.
