Your motherboard uses an Intel 1GB Ethernet controller. So try adding IntelMausi.kext to your bootloader‘s kext folder.
Here is what I did. But I can't make it work still.

Copy the IntelMausi.kext to EFI\OC\kexts
Open propertree, take a snapshot of my efi folder and save the config.plist.
Reinstall Catalina.

The installation went through w/o any problem. But there is no network adapter shown in system preferences\network.

Did I miss anything?

Thanks.

Did you check in System Information under Ethernet to see what it shows?

Did you try adding the Ethernet device manually in System Preferences > Network pane?

In the system information, it says ther is no ethernet card installed.

in the network pane, when I tried to add a card. It gave me an error saying there is no card.

DigiAU, attached is my last Catalina EFI folder for Gigabyte Z490. Back up your EFI from the disk you are booting from. If you have a fixed UHD630 graphics working, edit my file/folder with that fix, save and try booting with it.

Also make sure to add your own MLB, SN and UUID under platform info.

***EDIT: since others may need it, attached files for Catalina added to main guide DOWNLOAD HERE.

OMG, IT WORKED !!! What a magic.

I see you are using iMac19.1 instead of 20.1. I don't know what other differences are.

Thank you very, very much for your help. Much appreciated.

Cheers.

19.1 was good for Catalina as far as this motherboard. I never got 20,1 to boot until OpenCore 0.6.5 (I think it was). Anyway, you can now have a working base if you choose to update OpenCore.

Also note (as I forgot to remove it) there is a kext called "AHCI_3rdParty_SATA.kext". This is for 3rd party optical drive support that I sometimes attach in my rig to burn DVDs.

Congratulations! and by the way, if you have the onboard graphics working, can you share the fix? (upload your EFI if possible). Thanks

I compared mine with yours and have all of my USB ports working (front and back). No, I can't install Catalina with iGPU. I put a 580TX into my system and it works. I leave it as headless but not sure if it's working or not. Is there anyway to tell?

Thanks again for your help.

OK... I thought you went with a dedicated video card. I never bothered with iGPU as I don't know anyone who was able to make it work when I researched and built this last summer.
