That'll teach me to read logs at 6AM .

get_key_path()
{
    case "${1}" in
        0|CERT_DEV) if [ -f "/PRE_GM_DEBUGGING_FEATURES_ENABLED__REMOVE_AT_GMC" ]; then
                        echo "/etc/uks/pubdevkey01.pem"
                    else
                        return 1
                    fi ;;
        1|CERT_1K)  echo "/etc/uks/pubprodkey01.pem" ;;
        2|CERT_2K)  echo "/etc/uks/pubprodkey02.pem" ;;
        *) return 1 ;;
    esac

    return 0
}

TL;DR: Nope, you're screwed. It was fun while it lasted, guys.
