You can specify your hosts file in your operating system configuration
file ('config.scm'):

https://www.gnu.org/software/guix/manual/en/html_node/operating_002dsystem-Reference.html#index-hosts-file

You can maintain your hosts file "by hand" in, for example,
/etc/my-hosts and refer to it from config.scm like this (untested):

------
  (hosts-file (local-file "/etc/my-hosts"))
