There are some settings found on Device Manager > Ethernet Driver > Advanced Tab.

Are there suggestions for any of these settings? or any suggestion to improve ethernet driver security?

In general, there's very little that involves configuring an Ethernet driver that can control security or privacy. The job of an Ethernet driver is to get data from the kernel, where it's formed into packets, and turn it into actual signals on the wire. The Ethernet driver doesn't generally have a lot of say in what data it gets; that job is handled by the kernel or the application.

Things that impact security are going to usually involve how the kernel handles packets and the network stack, such as SYN cookies or spoofed packet handling, or things at a higher level, like the use of TLS. There could be settings that impact performance (such as checksum offloading) and therefore impact the ability of the kernel to handle more packets in a DoS attack, but generally those settings have sane defaults and the impact isn't going to be that substantial. You are also not going to be able to stave off a substantial DDoS attack by controlling these settings anyway.

So overall, I wouldn't think of any of these settings in terms of security or privacy. It's probably sufficient to make sure you're applying security updates on a regular basis and to think in terms of higher level things (e.g., using only HTTPS websites, avoiding running sketchy programs, and similar).
