resource meraki_devices_appliance_uplinks_settings ipv6 dynamic causing additional changes

[finkjordanj]

Prerequisites

• Have you tested the operation in the API directly?
• Do you have the latest Terraform provider version?
• Review the compatibility matrix before opening an issue.

Describe the bug
When applying the appliance uplink settings via a module built. The ipv6 SVI entry is set to dynamic on any plan or apply seems to trigger "changes" to the address, gateways, nameservers. Would expect if this set to dynamic that it would handle not requiring a change every time to those entries since it doesn't appear to store those values.

Expected behavior
If ipv6 svi on wan interfaces set to dynamic that the address/gateway/nameservers would not require updates.

Screenshots
My modules code just hardcodes the ipv6 to dynamic.

resource "meraki_devices_appliance_uplinks_settings" "primary_mx_appliance" {
  count = var.primary_mx != "" ? 1 : 0

  serial = var.primary_mx
  interfaces = {
    wan1 = {
      enabled = true
      pppoe = {
        enabled = false
      }
      svis = {
        ipv4 = {
          address         = var.primary_isp1_connections.operations == "static" ? "${var.primary_isp1_connections.ip_address}/${var.primary_isp1_connections.subnet}" : null
          assignment_mode = var.primary_isp1_connections.operations
          gateway         = var.primary_isp1_connections.operations == "static" ? var.primary_isp1_connections.gateway : null
          nameservers = var.primary_isp1_connections.operations == "static" ? {
            addresses = var.primary_isp1_connections.dns_list
          } : null
        }
        ipv6 = {
          assignment_mode = "dynamic"
        }
      }
      vlan_tagging = {
        enabled = false
      }
    }
    wan2 = {
      enabled = var.primary_isp2_connections.key != "null" ? true : false
      pppoe = var.primary_isp2_connections.key != "null" ? {
        enabled = false
      } : null
      svis = var.primary_isp2_connections.key != "null" ? {
        ipv4 = {
          address         = var.primary_isp2_connections.operations == "static" ? "${var.primary_isp2_connections.ip_address}/${var.primary_isp2_connections.subnet}" : null
          assignment_mode = var.primary_isp2_connections.operations
          gateway         = var.primary_isp2_connections.operations == "static" ? var.primary_isp2_connections.gateway : null
          nameservers = var.primary_isp2_connections.operations == "static" ? {
            addresses = var.primary_isp2_connections.dns_list
          } : null
        }
        ipv6 = {
          assignment_mode = "dynamic"
        }
      } : null
      vlan_tagging = var.primary_isp2_connections.key != "null" ? {
        enabled = false
      } : null
    }
  }
}

The output of my plan after an apply is already done.

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform will perform the following actions:

Additional context
I have my ipv4 also set to dynamic but those interfaces dont seem to require an updates.
