How about increasing the number of laps for practice up to ten. That will give time to set up not only wings etc but changes to engines, fuel and tyres.
You don’t need more laps for engine changes, it’s either new or old. There is no change to setup. Fuel will be almost exactly the same each time as well. Also, don’t only do one type of tires, do SS, S and M to get tire/performance readings on each tire. And then just write down your setup so next time you race there you can find the perfect setup easier.
