NetworkManager is now able to configure veth interfaces throught the NMSettingVeth. Veth interfaces only have "peer" property.
Veth connections cannot do "reapply" if the peer property has been modified. In order to update the peer profile, NetworkManager needs to deactivate the veth interface and activate it again with the new peer.
