Sometimes, the installer makes a BIOS-compatible installation which fails to run from UEFI. ... When the firmware supports both options, they are available, and the BIOS installer is usually the default. Another approach is to tweak your firmware settings to disable CMS (Compatibility Support Mode) and other compatibility features so that only the UEFI installer is available and try re-installing Guix to ensure it installs UEFI.

I’ve tried with both UEFI+CSM and UEFI-only, and get the same unbootable install either way.

The fix might be as simple as choosing a different USB boot option before running the installer. I typically have two boot options before running the installer from the USB: one is for UEFI, while the other is for BIOS.

I don’t have any option similar to that.

Secure boot is disabled in the BIOS.

You might want to try enabling it and see if any other options become available in the firmware settings. For example, if I reset my laptop firmware, all boot options are usually gone. I need to enable secure
boot and choose "Select a UEFI file as trusted", which becomes
available only with secure boot enabled. I can add a path to a ".efi"
file there.

My BIOS doesn’t have any option like that. Since the GRUB payload from Guix is the only file on the ESP, and is unsigned, I don’t think enabling Secure Boot is likely to solve this.
