There can be some setup work designed, e.g., to specifically get the most out of tyres in a single lap or in a short stint (like Q3). Example: if the tyres long getting into temperature, tyre pressures may be adjusted, suspension angles can be modified and wings "clicked down" to achieve greater slip angles and force heat in the tyres. This may not be good for race as it could generate too much degradation too soon and inconsistent stints. But, I might be wrong, but I believe that now the cars don't go to "parc fermé" after qualifying and, therefore, all specific adjustments for qualifying may be changed to revert to a better and more consistent race setup.
Another thing, CG height is higher with heavier fuel loads and this may influence the ideal suspension setup. Same goes to different tyre pressures, that vary the spring rate of the tyre itself, needing other spring rates for ideal performance.
