Can a cooling system pressure test CAUSE problems?

Hi CTC folks. I have a question about pressure-testing a cooling system. My 23 Bronco Sport Badlands has a known issue. The water pumps fail. Anyone with a Bronco Sport lives in fear it will strike them. Some owners have had 5 water pumps, proving Ford never dealt with the underlying issue, but just puts in known-bad water pumps as replacements. My coolant is now a bit under the MIN line when checked according to the manual’s instructions. About a half inch under. I plan to have the system “pressure checked.” Could that pressure test possibly damage other things? The vehicle is 29 months young with 12K miles. Any insights are welcome. (I have a great dealer who will do the work). No visible leaks. Car has heat and temp seems about normal. Possibly a bit longer to warm up than I’d expect. Thx
