man NetworkManager.conf

/etc/resolv.conf Processing Mode

By default, NetworkManager will update /etc/resolv.conf to reflect the name servers provided by currently active connections.

This behavior can be changed by setting the "dns" element.

In order to configure NetworkManager not to touch /etc/resolv.conf, set the following in the "[main]" section of /etc/NetworkManager/NetworkManager.conf:

[main]
...
dns=none
rc-manager=unmanaged

Once this is done, /etc/resolv.conf can be maintained manually as described here Manual /etc/resolv.conf Configuration.
