I'm going to take a shot at this. There's another example in the
guix-maintenance repo for berlin and some other machines

             ;; Connection to the DMZ for public access
             ;; This is a 1G port only
             (static-networking-service "eno1"
                                        "141.80.181.41"
                                        #:netmask "255.255.255.0"
                                        #:gateway "141.80.181.1")
             ;; This is a 10G port.
             (static-networking-service "enp129s0f0"
                                        "141.80.181.40"
                                        #:netmask "255.255.255.0")
             ;; Connection to build nodes
             (static-networking-service "eno3"
                                        "141.80.167.131"
                                        #:netmask "255.255.255.192")


So for what you've posted I would guess the following:
(It doesn't look like the static-networking-service allows you to use
DHCP to receive an IP address)

(static-networking-service "eth0"
                           "10.x.y.z"
                           #:netmask "255.0.0.0"
                           #:gateway "10.9.38.65")
