The way to do this may not be obvious unless you've done it before.
Here's an example of how I do this in my own operating system config
(for details, see '(guix) Service Reference' for the documentation of
the 'modify-services' syntax):

--8<---------------cut here---------------start------------->8---
(define %modified-desktop-services
  (modify-services %desktop-services
    (guix-service-type config =>
                       (guix-configuration
                        (inherit config)
                        (substitute-urls
                         '("https://hydra-mirror.marusich.info"
                           "https://mirror.hydra.gnu.org"
                           "https://hydra.gnu.org"))))))
--8<---------------cut here---------------end--------------->8---

Then you just declare the services as usual, for example:

--8<---------------cut here---------------start------------->8---
(operating-system
 (services (cons* (tor-service)
                  (gnome-desktop-service)
                  (xfce-desktop-service)
                  %modified-desktop-services))
--8<---------------cut here---------------end--------------->8---
