The be achieved by using Drupal\Core\Entity\EntityTypeManagerInterface.

use Drupal\Core\Entity\EntityTypeManagerInterface;

class MyForm extends FormBase {

 /**
  * The storage handler class for files.
  *
  * @var \Drupal\file\FileStorage
  */
 protected $fileStorage;

 /**
  * This is an example.
  *
  * @param \Drupal\Core\Entity\EntityTypeManagerInterface $entity
  *   The Entity type manager service.
  */
  public function __construct(EntityTypeManagerInterface $entity) {
    $this->fileStorage = $entity->getStorage('file');
  }
  ....
 }

From there you can update the File::load($fid) to $this->fileStorage->load($fid)
