JSON example for not changing IP, or using DHCP

We are failing over our VPGs without changing IP addresses, keeping a static IP that has already been configured in the OS.  I had ran a scipt to update all of our VPGs with updated vmware networks, and in doing so I set some NIC settings that shouldn’t be set.  Now I’m curious if I can fix this.  Basically I ran this for the VPG Settings for every one of our VMs:

$VMNICJSON = 
"    {
    ""Failover"":{
    ""Hypervisor"":{
        ""DnsSuffix"":""$VMNICFailoverDNSSuffix"",
        ""IpConfig"":{
                ""Gateway"":"""",
                ""IsDhcp"":""false"",
                ""PrimaryDns"":"""",
                ""SecondaryDns"":"""",
                ""StaticIp"":"""",
                ""SubnetMask"":""""
            },
        ""NetworkIdentifier"":""$VMNICFailoverNetworkIdentifier"",
        ""ShouldReplaceMacAddress"":""false""
            }
        },
    ""NicIdentifier"":""$VMNICIdentifier""
    }"

Which made it look like this in the GUI in the NIC settings for each VM in all of our VPGs:

Edit Selected vNICs

Network: Proper-Network-Here-8921

Create new MAC address?  No

Change vNIC IP Configuration? Yes, STATIC

IP Address xxx.xxx.xxx.xxx  (Literally, all x, no numbers)

Subnet Mask xxx.xxx.xxx.xxx

I’m basically curious how I should format that JSON to change the “Change vNIC IP Configurtion?” to “No”

I’ve tried removing the entire “”Ipconfig””:{} section, and tried again by changing “”isDhcp”” from false, to just “””” like the other parameters.  Neither seemed to do the trick.  So far, the only way I can figure out how to fix this is to edit each VPG and and all of the VMs from the UI.  Thanks for any help you may have.
