Hey y’all! 
The setup
I’ve got a Raspberry Pi 4 running the latest beta 64 bit version of Raspberry Pi OS Lite taken from the official servers, with HomeAssistant Supervised running on top as per this community guide.
The issue
It works perfectly overall and doesn’t even show the unsupported warning if that matters, but it’s my assumption that NetworkManager conflicts with default RaspiOS settings or something along these lines because the IP address related settings in HA’s UI don’t work, and nmcli shows the eth/wlan interfaces as unavailable.

Extra info
The only network related setting that’s changed from default as far as I’m aware is /etc/wpa_supplicant, which contains the following and was necessary for wifi to work with ssh since I run it headless and with no readily available ethernet cable:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=BR
network={
[redacted]
}
The files mentioned here look exactly the same bar the uuid as well.
I do realize this is pretty niche and that I’m fully responsible for choosing to do it this way but searching didn’t turn up much I can make sense of so I’d appreciate some pointers if someone’s got any idea how to get it working or has been in a similar spot.
If you’re still with me, thanks a lot for reading!
