Reduce supply without triggering weaning?

I’m 9wpp, just reduced pumping to 6ppd a few days ago and worried my supply is still increasing. I just pumped almost 19.5 ounces combined (almost 9 in one side, 10.5 on the other). I want my supply to regulate or even reduce a bit without triggering weaning. Does anyone have any advice? I’m scared to reduce any more pumps but also scared of my supply increasing and getting mastitis.

Sorry, edit to add that my average daily output is about or more than 80 oz a day. My highest being 95 oz.
