The Gen4 management port speed can be configured from the system BIOS.

Using the KVM or Serial Over LAN enter the BIOS page.

Step 1) Select Intel NIC

Find the Intel NIC in the Advanced tab as shown below

Step 2) Select Device Level Config

Select Device level Configuration as shown below

Step 3) Select Port Option Configuration

Select Port Option Configuration as shown below

Step 4) Choose the port configuration mode

Select the target port mode

Step 5) Save & Exit

Press ESC key multiple times and go to Save & Exit

Select YES

Step 6) Confirm port mode

System will reboot

Wait for FMADIO OS to boot then confirm the setting using

ifconfig -a

Expecting multiple interface named phy10, phy11, .. phy17  depending on the number of ports

In this example we configred 2×4×10G, total of 8 ports, thus expecting phy10 - phy17 present on the system

Example output shown below
