Not sure about your first question. Maybe create your own fork and regularly rebase it? Guix will not be very happy with that I think, but it should work.
To pass --no-substitutes, you can pass it to guix-daemon, or remove the authorized keys from /etc/guix/acl. The second option lets you download substitutes for fixed output derivations (basically source tarballs), so it's easier in case some of those tarballs disappear from their original location. I think the first option is selectable from the installer, but I might be wrong. Otherwise, stop guix-daemon from herd and run it manually with your options.
