You can go at this from the other direction to only get the Posts:
$posts = Post::whereHas('category', function ($query) {
$query->where('displayed', 1);
})->get();
Assuming you have the inverse of the relationship setup Post -> Category. This is saying get all Posts having Category where displayed equals 1.
Adjust the relationship name as needed.
