Default Sunroof cavitation and air pressure

I have a 2017 Cherokee Trailhawk. When I'm driving down the freeway and have the solid roof panel fully to the rear I get a liot of cavitation and the frequency is quite painful. Also, if solid panel not fully to the rear, my ears can get a lot of pressure. I think most occurs while I'm driving, so I think it is the wind sucking the air out when I open the sunroof.
Will a solid windscreen reduce of fix these issues? Is putting the solid panel fully to the rear while driving at speed not doable because of the size of the opening?
Should I just refrain from opening my sunroof while over a certain speed?
Thank you.

I would repost this in the KL section, you posted in the XJ section. We are lucky to have power windows here, let alone a power sunroof.

The early model Grand Cherokee WJ had a similar issue with its modest sunroof when fully open. Chryslers solution was to add a stop that prevented sunroof from fully opening by about three inches.

I pop open the rear windows about half an inch and the pressure drops instantly.
