Connecting HomePod using different password than my iPhone

I'm trying to connect my HomePod to the network in my university accommodation. It is currently connected but there's a different network it would be easier to use it on. This network requires you to register the MAC address with the university and then use a different password that it gives you for each device. My phone is connected to this network but when I try to move the HomePod to it, it uses the password from my iPhone.

Is there any way to use a different WiFi password between the two?
