Scope FortiGate-VM.
Solution

All FortiGate-VMs use virtual network cards that only support 'auto' as the only option.

This is an expected behavior and by design, because 'speed negotiation' is only applies when using a 'physical network card'.

VMs do not have direct access to the 'physical network card' because they only use 'virtual network cards'.

 

This configuration is available on the older FortiOS version, but VMs still do not have direct access to the physical network card speed negotiation.
