How to create "No Zone" for the standard IP address

Hi, Azure Portal offers 5 options when creating a new public IP address
No Zone
Zone Redundant
Actual Zone like 1, 2, 3

When I try to create a public IP like below
resource “azurerm_public_ip” “my_ip” {

  name = "myip"

  location = "EastUs"

  resource_group_name = "rgname"

  sku = "Standard"

  allocation_method = "Static"

}

If I do not put the zones parameter, it will create a zone-redundant IP address. How do I create a “No Zone” IP address here?
I have tried a couple but they did not work
zones= -->It ends with zone-redundant
zones={} -->It complains the zones name needs to be a string list.
