Intel Ethernet Controller I226-V link issue

[select2]

Hi Colleagues!

I have a Lenovo ThinkCentre M920q Tiny i5-8600T 32GB RAM 512GB NVMe with built in Intel Ethernet Connection (7) I219-LM [8086:15bb] (rev 10) and installed Proxmox 8.4.1.
All works fine, but I need to add a secondary NIC. I bought M.2 Intel Ethernet Controller I226-V [8086:125c] (rev 04) from https://www.aliexpress.com/item/1005008904049465.html.

The new card is visible on the Proxmox, but there is no link:

I tried to change the switch port, cables - it doesn't works.
But when I booted from the Ubuntu Live USB - the link is up on both NICs! Immediately and without any additional options.
When I reboot to ProxmoxVE, I see for the short time link is up, and then link is down when the kernel starting.
Additional info:

I assume the problem with the Intel igc driver.
Could you help me please to solve the issue?

Thanks in advance!

I found the issue - it was my stupid mistake.
Need to add the configuration for the new interface to the /etc/network/interfaces file:

auto enp2s0
iface enp2s0 inet manual

And bot links is up now.
