Forwarding error detection - FEC

Hello,

I try to understand how i can change the FEC parameter on a server. It's a dell r740xd with esxi installed on it.

The network card is a Mellanox Technologies MT27710 Family [ConnectX-4 Lx] (25G with twinax) version 14.32.20.04.

Is this nic parameter needs to be changed in esxi directly ? if yes how ? 

Or we can change it directly from idrac ?

Thks for your help
