Yeah there is. I think it’s itlwm.

What part I got an issue with: have to set SecureBootModel to 'Disabled' since i am using AirportItlwm for monterey

Wifi is a little unreliable a few minutes after boot (waiting for AirportItlwm to be stable release)

Intel I219-LM Ethernet - IntelMausiEthernet

Try installing this kext: https://github.com/acidanthera/IntelMausi/releases

for worked intel ethernet require IntelMausi.kext (https://github.com/acidanthera/IntelMausi), for check internet connection in installer open terminal utility and type ping google.com or ping apple.com if packets not lost - have success internet connection.

Also, I want to know if the integrated GPU and Network will work, for the GPU if the complete VRAM will work and for the network I have seen this patch and I don't know if it works : https://github.com/acidanthera/IntelMausi - The card is an Intel I219-V

Ethernet (IntelMausi)

Hope you are using the Lates Release of IntelMausi. Have you added the required device property or bootargs?

For ethernet you would need IntelMausi kext as it is an intel chip. https://github.com/acidanthera/IntelMausi

Your board appears to have the Intel I219-V Ethernet chipset, so it should work with IntelMuasiEthernet... unless your copy of the kext is just too old? It's had a name change within the past 8 years, after all. You can find the latest version here: https://github.com/acidanthera/IntelMausi/releases
