Furrion a/c. noise reduction

[Sled dog]

I have a 2023 Surveyor Legend 240BHLE with the Furrion rooftop a/c unit. While running, the unit is extremely loud so I'm trying to figure out how to reduce the noise. I've looked at the RV Airflow system but I'm not sure how it would work on our unit because it has no duct system, only the fan side and the return side. Has anyone figured out how to reduce the noise from the ac unit? RV Airflow said it would require a special order insert be made using various internal measurements. Any advice or suggestions are greatly appreciated. For reference, I've attached three photos of the unit.
