I suppose the path can be found with:
ls /gnu/store/*/ucode5.fw
/gnu/store/l7k3psmq08ad40swi1kf9as4bjizlz7i-openfwwf-firmware-5.2/ucode5.fw
/gnu/store/yjycspnbxyafys84hn4f1phjy37fai20-openfwwf-firmware-5.2/ucode5.fw

So the path would be:
export GUIX_PACKAGE_PATH=/openfwwf-firmware-5.2

Is that correct?
