LarkBox X network port 2,5gb doesn't work

Hi,

I can see after sometimes with this item that 2,5 ethernet port is not working.

I have installed proxmox to run home assistant and i can see that 2,5gb is not active. I have just entered in BIOS and i can`t find any menu where this ethernet port appears to activate it.

Is there any problem with that or have i to make some action that i don`t know about it?

Thanks in advance

Regards,
