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.
