Use Rainex on Model 3 windshield?

According to Model 3 owner’s manual, “Do not use windshield treatment fluids. Doing so can interfere with wiper friction and cause a chattering sound.” I am having my car ceramic coated which includes 2 layers of “Rain” on the windshield. Wondering if I should decline this service?
