Question - Pressure Washer PSI

Hey all,

Just a quick question. I got a Hyundai Palisade with a matte finish, and I wanted to use a 2200 PSI Ryobi Power washer on it. I have the Ryobi dial nozzle that goes has multiple degrees including 40 but worry about the PSI not lowering enough to not hurt the paint. I did see Ryobi makes now a specific power washer aimed at cars but wondered if that would be silly to purchase that just to lower the PSI. I believe the nozzles also lower the PSI making it safer, but I wanted to reach out to see if anyone knew on here.

Any help is greatly appreciated.
