Debug Output/Panic Output

from terraform plan:

resource "azurerm_linux_virtual_machine" "management" {
        id                                                     = "/subscriptions/1234/resourceGroups/dev-rg/providers/Microsoft.Compute/virtualMachines/dev-management-vm"
        name                                                   = "dev-management-vm"
      ~ vm_agent_platform_updates_enabled                      = false -> true
}

from Azure Api:
GET https://management.azure.com/subscriptions/1234/resourceGroups/dev-rg/providers/Microsoft.Compute/virtualMachines/dev-management-vm?api-version=2023-03-01


"provisionVMAgent": true,
  "patchSettings": {
     "patchMode": "AutomaticByPlatform",
     "automaticByPlatformSettings": {
        "bypassPlatformSafetyChecksOnUserSchedule": false
     },
     "assessmentMode": "AutomaticByPlatform"
  },
"enableVMAgentPlatformUpdates": true

Expected Behaviour

vm_agent_platform_updates_enabled should be true as it is already set true on the resource

Actual Behaviour

vm_agent_platform_updates_enabled is seen by Terraform as false but it is set true on the resource
