Build configuration specific DefaultEngine.ini

In our team, we typically use two different configurations for testing: development and shipping. The development build configuration is used by the developers while the shipping configuration is mainly used by the quality assurance team. When using the development configuration we want the framerate to be as high as possible in order to be able to coarsely detect whether a new feature is slowing down the application. For that reason, we disabled the fps cap in Project Settings -> General Settings -> Framerate which results in DefaultEngine.ini being changed accordingly.
However, when using the shipping build configuration, fps should be capped so that the engine does not consume all the GPU. So I’m wondering whether there is a way to change the settings contained inside DefaultEngine.ini based on the build configuration.
