Terraform Configuration Files

resource "aws_instance" "mysql" {
  ami                     = var.ubuntu22lts-ami
  instance_type           = "t3a.small"

  ebs_block_device {
    delete_on_termination = true
    device_name = "/dev/sdf"
    volume_size = 8
    volume_type = "gp3"
  }
}

or

resource "aws_instance" "mysql" {
  ami                     = var.ubuntu22lts-ami
  instance_type           = "t3a.small"

  ebs_block_device {
    delete_on_termination = false
    device_name = "/dev/sdf"
    volume_size = 8
    volume_type = "gp3"
  }
}

Steps to Reproduce

Try changing delete_on_termination in the ebs_block_device block, and run terraform plan. You should see a change with changing the value in AWS, but no matter the option, it detects no changes.
