I don’t think that there is any way to do this, but to be honest, I don’t know.

You would somehow need to capture the user ID that was just created and before ACF tries to save the values.

I don’t know if any of this will work.

use "new_user" for the post ID in your form.

// i'm using a class here so I can store a value in one action/filter
// and retrieve it in a different action/filter
// you could also do this using a global variable
class my_custom_acf_save_user_form {
  
  private $user_id = false; // will store the user id just saved

  public function __construct() {
    add_action('user_register', array($this, 'user_register', 10, 1);
    add_filter('acf/pre_save_post', array($this, 'pre_save_post', 10, 1);
  }  // end __construct

  public function user_register($user_id) {
    // capture the id of the user just created
    $this->user_id = $user_id;
  } // end user_register

  public function pre_save_post($post_id) {
    if ($post_id == 'new_user' && $this->user_id) {
      $post_id = 'user_'.$this->user_id;
    }
    return $post_id;
  } // end pre_save_post

} // end class

new my_custom_acf_save_user_form();
