I personally use
--8<---------------cut here---------------start------------->8---
  (require 'tramp)
  (connection-local-set-profile-variables
   'guix-system
   '((tramp-remote-path . (tramp-own-remote-path))))
  (connection-local-set-profiles
   '(:application tramp :protocol "sudo" :machine "hostname")
   'guix-system)
--8<---------------cut here---------------end--------------->8---
for tramp on my own machine.  The symbol 'tramp-own-remote-path uses the
login shell of the target to determine the environment to use, so is
well suited for guix.  You may need to adjust the :protocol and :machine
keys of the connection-local-set-profiles call for your use case though.

Best,
