I'm afraid not. Bumping the version of glibc is not a trivial package
update in Guix, it means almost all packages need to rebuild (rebuild
the world).

If you really need it, you may inherit from a existing glibc package,
update to 2.35 and use it. But you may need extra patches to make it
work well.

I'd suggest you use docker and run some distro with glibc 2.35(FWIK Archlinux).
