I found this in an old post which could possibly makes my broadcom bcm4324 work on mac os, but as it is old, it's not working on our system mainly because
Apparantly the bcm 4311 is close enough to be used by the bcm4324, unfortunately with recent updates, mac os deprecated the bcm4311.kext and instead we have the bcm4316.kext, if it's close enough to be used by the bcm4324 it should only need a fake device in config.plist to spoof the bcm4324 as a 4316 and should be working, I'll try that later
The broadcom module in the vaio is not natively supported by mac os. For now I use a wifi usb dongle with the help of https://github.com/chris1111/Wireless-USB-OC-Big-Sur-Adapter to have a working internet on my laptop
