It might be true, the only real way to find out is to test.
This is a compile time option so that would require a recompile of apache. Download the srpm, install it, modify the source, create a patch file, apply the patch file in the .spec file, rebuild the RPM, install the RPM. (That's a very quick description for a somewhat longer process.) Here is a more complete example.
Or you could just download the source, compile it, and install it. Which might be a better choice for testing purposes. I'd go the extra mile and create the RPM. You always want to create a re-producible environment, especially in a very high traffic situation.
