Here's a link¹ to my pinebookpro config. The short version is you need
to change the bootloader to use grub-efi (apparently I went with
grub-efi-removable-bootloader but I don't remember why)

  (bootloader
    (bootloader-configuration
      (bootloader grub-efi-removable-bootloader)
      (targets '("/boot/efi"))
      (keyboard-layout keyboard-layout)))

And you need to add /boot/efi as a vfat file system.

  (file-systems
    (cons* (file-system
             (device (file-system-label "Guix_image"))
             (mount-point "/")
             (type "btrfs")
             (options "compress=zstd,discard,space_cache=v2"))
           (file-system
             (mount-point "/boot/efi")
             (device (file-system-label "GNU-ESP"))
             (type "vfat"))
           %base-file-systems))

Towboot should pick up grub just fine and you can boot with that.
