Is it possible to get the terraform state file from the remote backend and set it for modifications

Question

I need to get the terraform state file from the backend GCS and to use it while I update the resource is it possible to overwrite the excising terraform state file and fetch it on need.

this is my main.tf

provider "google" {
    project = var.project
    region  = var.region
    zone    = var.zone
  }

data "google_compute_default_service_account" "default" {
}


#create instance1
resource "random_id" "bucket_prefix" {
  byte_length = 8
}

#create instance
resource "google_compute_instance" "vm_instance" {
  name = var.instance_name
  machine_type = var.machine_type
  zone         = var.zone
  metadata_startup_script = var.script
  allow_stopping_for_update = true
  #metadata = {
   # enable-oslogin = "TRUE"
  #}
  service_account {
    email  =  data.google_compute_default_service_account.default.email
    scopes = ["cloud-platform"]
  }
 
  boot_disk {
    initialize_params {
    image = var.image
    #image = "ubuntu-2004-lts" # TensorFlow Enterprise
    size  = 30  
    }
  }

  # Install Flask
 
 
  tags = ["http-server","allow-ssh-ingress-from-iap", "https-server"]

  

  network_interface {
    network = "default"
    access_config {
    }
  }
  guest_accelerator{
    #type = "nvidia-tesla-t4" // Type of GPU attahced
    type  = var.type
    count = var.gpu_count
    #count = 2 // Num of GPU attached
  }
  scheduling{
    on_host_maintenance = "TERMINATE" 
    automatic_restart = true// Need to terminate GPU on maintenance
  }
  
}

This is my variables.tfvars:

instance_name   = "test-vm-v5"
machine_type    = "n1-standard-16"
region          = "europe-west4"
zone            = "europe-west4-a"
image           =  "tf28-np-pandas-nltk-scikit-py39"
#image           = "debian-cloud/debian-10"
project         = "my_project"
network         = "default"
type            = ""
gpu_count       = "0"

I wanted to create multiple instances by changing the variables.tfvars and need to modify the instance on the basis of the name of vm.
