For the current reports the only option is either to go into the pivot line item report in which you can select rent only which eliminates the service fee or booking summary which includes the service fee. The problem with the line item report is that you cannot prorate rent (so if you have a 3month booking there is no way to just get the revenue for that month).
There has to be some way to be able to create an accurate report to see what revenue is, without Airbnb fees in it.
