I don't think there is an option for this. It would certainly be helpful
if there were one.

Currently, my workaround is to create a manifest listing packages to be
installed:
https://notabug.org/alexvong1995/guix-package-declaration/src/master/manifest
and run "guix package -m ./manifest" instead of "guix package -u".

[emacs-guix users can run the interactive function `guix-apply-manifest'
instead.]

When there is a package without substitutes, I will stop the command,
comment out the said package and re-run the command. I will also re-try
after a few days when more substitutes are available.

Hope this help!

Cheers,
Alex
