Another option is to add to your ~/.zshenv the line:

    setopt no_global_rcs

And then if desired in your ~/.zprofile add:

    setopt global_rcs

This pair of commands placed in these two files will disable reading of
/etc/zprofile and then re-enable reading of /etc/zshrc and /etc/zlogin,
without needing to remove system files (which might re-appear on an update
anyway).
