Someone might have better suggestions but until then here's my thoughts on 
it:

There's some step-by-step instructions for setting up a grub-password and 
then setting a path to a luks keyfile in grub on a system using Libreboot 
and Parabola here:
https://wiki.selfhosted.xyz/doku.php?id=it:computer_setup:encrypted_parabola_installation_guide#boot_configuration

This could possibly be adapted to GuixSD. In short the steps involved 
(without setting up grub's password authentication) are:

-generate key and add to your luksdrive
  dd bs=512 count=4 if=/dev/urandom of=/etc/my_cryptkey iflag=fullblock
  cryptsetup luksAddKey /dev/sda1 /etc/my_cryptkey
-Regenerate initramfs (using the mkinitcpio bash-script)
  zile /etc/mkinitcpio.conf
  FILES="/etc/my_cryptkey"
  mkinitcpio -p linux-libre (or linux-libre-lts or linux-libre-grsec or all of 
them)
-Then add a configuration line to your grub config's default menu-entry on 
the linux-line:
  linux /boot .... cryptkey=rootfs:/etc/my_cryptkey

For details on setting up the password etc see the link above.

Hopefully, there is a way to define this in a guile system declaration.
