It's been log since I have seen this 7-mode stuff, so I might be wrong here. Simply looking at the image you shared, so there is current IP of that VIF and there is an option for partner interface (Under failover mode: shared). For partner interface, shud be ok b'cos it will only come into affect when the partner failed over to the current Node. However, for the IPv4 there, isn't that serving any protocols/clients ? If it's not then you can go ahead but you need to ensure the changes are reflected in the /etc/rc file as well, to ensure it stays persistent across reboot.
