I saw that this 2.5 GbE chip has problems interoperating with some other networking gear.
I read that intel did not fix the issue in current B2 version.Maybe rtl8125B is the right selection.
this is from https://wccftech.com/intel-foxville-i22 ... -affected/

In the networking performance tests conducted by our source, the B2 stepping on a retail Z490 motherboard delivering speeds of around 255 MB/s (2.05 Gbps) transfer speeds (without switch) and even worse speeds of 144 - 194 MB/s (<2.0 Gbps) when using a Netgear XS505M switch.

In comparison, a Z490 motherboard with a 3rd party 2.5 GbE networking switch delivers consistent speeds with our without the use of a switch. From what we have managed to gather, it looks like a large list of Z490 motherboards, primarily from ASUS and Gigabyte, could be affected by this issue since they're still relying on the B2 stepping of the chip. Other Z490 vendors rely on 3rd party net-working controllers so this issue is nonexistent for them.
