Is there a PrusaSlicer setting to adjust the first layer of supports?

My least favourite job after a print is removing the first layers of support from the smooth PEI buildplate. The print itself pops off nicely from the plate, but usually there is a bunch of support that stays stuck to the plate.

I was wondering if there's a setting in PrusaSlicer to tweak the first layer of supports, so that the support is more likely to come off the plate instead of sticking behind-- making it a solid layer, for example.
