Stop sharing Wi-Fi password with iCloud for a single Network

Hi,

I have several Apple devices (iPhone, iPad, MacBook, Apple Watch) that I would like to connect to a Wi-Fi connection. I live in a complex where the landlord provides the Wi-Fi. For this, each device has to be registered with the MAC address and a separate Wi-Fi password is automatically generated for each device, which I cannot change and only works if the device logs in with exactly the matching MAC address. My problem now is that when I log in with the iPhone, for example, the password that only works for the iPhone is transmitted to all other devices and I have to log in again with each device each time. In general, of course, I love the feature that passwords are automatically synced between all devices, but for this particular Wi-Fi network, I would like to disable that. Is there a solution for this ?

Cheers

Tom
