The situation in which you don't want to show some field suggests badly designed form. You could feed some argument(s) into it's __construct to make it conditional (say, include/exclude some fields) or you could just create separate Form classes (which is, in my opinion, a bit overkill).

I had common case few months ago when form differed when user inserted/updated records. It was something like this:

...
public function __construct($isUpdateForm){
    $this->isUpdateForm= $isUpdateForm;
}

public function buildForm(FormBuilder $builder, array $options){
    ....
    $builder->add('some_filed', 'text', ..... );

    if ( $this->isUpdateForm ){
        $builder->add(.....);
    }
    ....
}
....

If for some reasons you're not able to refactor form class you could still display unwanted fields but wrap them into

which has CSS display:none attribute. That way "they are still there" (and by all means are processed normally) but are not visible to user.

Hope this helps...
