3 Zone HVAC - Can they be blocked to be separated?

Hello. I have a 2023 Forest River Riverstone Legacy 442MC. I have three climate zones which feed into the overhead duct and vent system for three rooms (bedroom, kitchen, living room). After a Firefly update the systems and temperatures seem to regulate a little better, but I still have some concerns.

The front bedroom is the smallest room by volume, but even with the bedroom HVAC unit completely shut off that room will heat and cool faster than the middle kitchen/dining room area when only running the middle HVAC system. Using my hand and a dry tissue as an unofficial test, I would say the velocity of air coming out of the bedroom vents matches the velocity of the air coming out of the kitchen vents when the kitchen HVAC unit is running. This ultimately ends up causing the bedroom to be much cooler or hotter than the temperature I have set for that zone since the kitchen HVAC unit is impacting the bedroom and is possibly robbing the kitchen zone from heating or cooling properly.

It is my understanding that the entire overhead duct/vent system is one large pathway. If that is true, has anyone else experienced the same issue as me and tried to stuff something in the ducts between zones so the air from each of the three zones is forced into those rooms instead of leaking throughout the entire system?

Thanks in advance for your help or suggestions?
