Not sure if this is an appropriate answer, but to customize the guix daemon
service field like described in the example here:

  https://www.gnu.org/software/guix/manual/html_node/Using-the-Configuration-System.html#System-Services

you would have to patch "gnu/services/base.scm" by adding a field to the
'guix-configuration' that would be then be passed to the
'#:environment-variables' option of 'make-forkexec-constructor' in
'guix-shepherd-service'.

HTH.
