How to configure eth0 to negotiate only on 100\1000 FD?

[shaybery]

I want to configure eth1 to be negotiation ON but I want it to
Advertised only link modes : 1000baseT/Full 100baseT/Full.
it means that eth1 will be negotiated only on 100\1000 Full duplex.

There is any way to do that (to change the Advertised link modes) ?
