I think the solution is to use ‘guix shell -D guix -CP’: that’ll give
you a container, where /usr/bin/guile-3.0 isn’t accessible, which
ensures there’s no interference.

(FWIW this is what I do, even on Guix System, for my development
environments.)

Does that work for you?

If your distro doesn’t support unprivileged user namespaces, which ‘-C’
relies on, you can fall back to ‘--pure’.
