I am running into the same issue as well.  This is on a foreign system
using Emacs and Tramp trying to call find on remote hosts that are not
Guix.

Is there maybe an easy way around this?  I tried:

--8<---------------cut here---------------start------------->8---
(connection-local-set-profile-variables
 'remote-system
 '((tramp-remote-path . ("/bin" "/usr/bin" "/sbin" "/usr/sbin" "/usr/local/bin" 
"/usr/local/sbin" "/local/bin"))))
(connection-local-set-profiles
 '(:application tramp :machine "host.example.com")
 'remote-system)
--8<---------------cut here---------------end--------------->8---

The connection will set the remote-path.  But rgrep will still invoke
find from a path in /gnu/store.


Cheers
