How can I hide certain properties in the response?

I don't want the attribute "hash" to appear in the response.
How can I hide certain properties in the response?
Thank you!

use Mango\Bundle\JsonApiBundle\Configuration\Annotation as JsonApi;

/**
 * @JsonApi\Resource(type="posts")
 */
 class Post 
 {
    /**
     * @JsonApi\Id
     */
    protected $uuid;
    
    /**
     * @JsonApi\Relationship(includeByDefault=true, showLinkSelf=false, showLinkRelated=false)
     */
    protected $comments;

    protected $hash;
 }

@eloygonzalez you have to import JMS serializer and use @JMS\Exclude()

use Mango\Bundle\JsonApiBundle\Configuration\Annotation as JsonApi;
use JMS\Serializer\Annotation as JMS;

/**
 * @JsonApi\Resource(type="posts")
 */
 class Post 
 {
    /**
     * @JsonApi\Id
     */
    protected $uuid;
    
    /**
     * @JsonApi\Relationship(includeByDefault=true, showLinkSelf=false, showLinkRelated=false)
     */
    protected $comments;

    /** @JMS\Exclude() */
    protected $hash;
 }
