It sounds like you think that saving a new scene will reset your EQs, but that is not the case.
Therefore, save your show and do a reset as described on page 83 of your manual.
After that, you should see/hear that there is no change when you disable flat EQs.

However, this should not have any effect, because your console is designed in such a way that the required computing power is always available for all processing components.
