This works for me.  I have configured berlin.guixsd.org with two network
interfaces by simply providing static-networking-service twice.  I’m not
removing any services from %base-services:

  (services (cons* …
             (static-networking-service "enp6s4f0"
                                        "141.80.181.40"
                                        #:netmask "255.255.255.0"
                                        #:gateway "141.80.181.1")
             (static-networking-service "enp0s8"
                                        "192.168.0.1"
                                        #:netmask "255.255.255.0")
             …
             %base-services))
