[TUTORIAL] Realtek 8125 NIC not working on Proxmox with X870E motherboard (no network)

If the kernel does not load the driver, this actually means that the driver for the device does not feel addressed.
Unfortunately I can't tell you why this is the case and I have a different motherboard so I can't reproduce it.
I would recommend that you stick with the older kernel for the time being and try the latest kernel as soon as new kernels are released by us.
