Yes. I have found that you can drill into a rock in the cement. The rock is often much, much harder than the cement. And that will greatly slow down a typical carbide drill without hammering.

Also be very sure the wall is not pre-stressed concrete. If it is you can severly compromise the structural strength. My daughter bought a fairly new house in Las Vegas. The garage floor is pre-stressed concrete and has a warning molded into the front main florr near the door that says to not cut or drill into it.
