thank you very much,
this is the final code if anyone need it : 

<?php

use Drupal\Core\Form\FormStateInterface;
use Drupal\Core\Session\AccountInterface;

/**
 * Implements hook_form_FORM_ID_alter() for node_exams_and_assignments_edit_form.
 */
function my_module_disable_editing_old_uploaded_files_form_node_exams_and_assignments_edit_form_alter(&$form, FormStateInterface $form_state, $form_id): void {
  // Get the current user.
  $current_user = \Drupal::currentUser();

  // Skip the custom logic if the user has the "administrator" role.
  if ($current_user->hasRole('administrator')) {
    return;
  }

  // Loop through the field_exams_assignments_files widget items.
  foreach ($form['field_exams_assignments_files']['widget'] as &$item) {
    if (is_array($item) && isset($item['#default_value']['target_id'])) {
      // Disable the file for non administrator users.
      $item['#disabled'] = true;
    }
  }
}

/**
 * Implements hook_preprocess_HOOK() for file_widget_multiple templates.
 *
 * Disable tabledrag for field_exams_assignments_files.
 */
function my_module_disable_editing_old_uploaded_files_preprocess_file_widget_multiple(&$variables) {
  // Get the current user.
  $current_user = \Drupal::currentUser();

  // Skip the custom logic if the user has the "administrator" role.
  if ($current_user->hasRole('administrator')) {
    return;
  }

  // Disable and hide tabledrag for non administrator users.
  if ($variables['element']['#field_name'] === 'field_exams_assignments_files') {
    unset($variables['table']['#tabledrag']);
    unset($variables['table']['#header'][1]);
    foreach ($variables['table']['#rows'] as &$row) {
      unset($row['data'][1]);
    }
  }
}

Hello  wombatbuddy → , thank you very much,

it dosn't work but i made some changes and i made it "disabled for all except the administrator", now it works.
there is a little issue : when the user upload files he can choose the weight to current uploaded files, i want to make it disabled.
