How to change DNS Server with CMD?

[Windows User]

By using the command below i managed to change the DNS server to cloudflare.
interface ip set dns "Ethernet" static 1.1.1.1

How can i changed not only the primary but the alternate DNS Server to 1.0.0.1
What is the command?

Update:
Booth these commands appear to be working perfectly.

netsh interface ip add dnsservers "Ethernet" address=1.0.0.1 index=1
netsh interface ip add dnsservers "Ethernet" address=1.1.1.1 index=1

netsh interface ipv4 add dnsservers "Ethernet" address=1.1.1.1
netsh interface ipv4 add dnsservers "Ethernet" address=1.0.0.1
