A bit late for the party, but one way to do it
would be to run Racket in a container, and as
usual export the necessary certs:

--8<---------------cut here---------------start------------->8---
# Create the container and expose the zoneinfo
./pre-inst-env guix environment -N -C --expose=/usr/share/zoneinfo --ad-hoc racket-minimal nss-certs coreutils libedit

export SSL_CERT_DIR="$GUIX_ENVIRONMENT/etc/ssl/certs" && export SSL_CERT_FILE="$GUIX_ENVIRONMENT/etc/ssl/certs/ca-certificates.crt"
--8<---------------cut here---------------end--------------->8---

I do things that way since there's a racket
program[0] I ran in a server; and it's convenient
on that regard...
