Start by reproducing `pip3 install etcd3` on the reported aarch64 SLES environment and inspect the grpcio build step, especially the missing `cc` command. Done means identifying whether python-etcd3 or its grpcio dependency needs a project change, and verifying installation on the affected environment.
