Yes.

There are several things to consider here.  By default, guix-daemon
creates a single job, so that single job will end up being built
locally, unless you spawn, say, two =E2=80=9Cguix build=E2=80=9D commands i=
n parallel
(the number of jobs is per client.)

Running =E2=80=9Cguix-daemon --max-jobs=3D0=E2=80=9D should force all build=
s to be
offloaded:

  https://www.gnu.org/software/guix/manual/html_node/Invoking-guix_002ddaem=
on.html

I *think* =E2=80=9Cguix build --max-jobs=3D0=E2=80=9D should give the same =
result.

Alternately, if you run =E2=80=9Cguix build --max-jobs=3D2=E2=80=9D, presum=
ably half of
the builds will be offloaded.

Let us know if that works for you.
