You can try this, will not check for any validation

$User = $this->Users->get($id) 

if($this->request->is(['patch', 'post', 'put'])){
    $User = $this->Users->patchEntity($User, $this->request->data);
    if($this->Users->updateAll(['username' => $User->username], ['id' => $User->id])){
       $this->Flash->success(__('The username has been changed));
    }
}
