No, the transitions occur even without turbo. In fact, the chip I tested on has no turbo at all, just 3.2 GHz nominal speed.
Also, disabling turbo would probably be a massive over-reaction, unless you really care out about 99.9th latency or something: the impact of these transitions is small (at worst a few %), while the benefit of turbo is large: 10s of %.
