Ubiquiti access point detected as Linux

I added 5 Ubiquiti Access Point (Ubiquiti firmware version 3.9.27.8537) and they are all detected as Linux, and not as Ubiquiti OS.

The os parameter should be detected as unifi and not as linux.

Now I am wondering of I can change the os parameter as even if I change it into the database it will be replaced at the next device discovery.

Thanks!
