There is no way to disable the hack I'm talking about. It simply nerfs any != alpha test (we optimize out != 0 which is the most common of these.) Also, alpha test is compared in a more lossy way and is more likely to compare incorrectly (but was broken entirely when we tried to compare it more directly, I think because it was forcing a lowp float.) This also affects color tests.

There's also the alpha test hack, which disables alpha testing entirely. That one you can change in settings.
