It is identical to Fabiosun and I think like him from my experience on my TXR40.
On my system. I lost Ethernet (i210 Intel) stopped working since Monterey. (I didn't disable the ports in the bios)
I remedied this problem with a USB C / ethernet 2.5 GB adapter.
This is an experience for you. No kexts regarding Aquantia and motherboard ethernet.
Connected your UBC C / Ethernet adapter like this from the start of the OSX to the ethernet connection natively.
For me, works very well, it is recognized natively from the start so it is possible to install the new system from the backup partition. It is with this method that I test Ventura with each time a clean install.
With Ventura, I will lose Bluetooth. At the time of today it no longer works but the wifi still works.
It is with this method (USB C / ETHERNET adapter) that I test Ventura with each time a clean install on an NVME on its dynamic partition. (Add Volume in Disk Utility)
