wpautop on custom Gutenberg blocks, can't remove wpautop?

Hello,
I created a Gutenberg block and it renders fine but it's adding <p></p> like wpautop is running on the block template. I tried using the standard:

remove_filter('the_content','wpautop');
remove_filter('render_block','wpautop');

But nothing happens!
What am I doing wrong?

Here is my code to create the block:

// Video Background Section
        $meta_boxes[] = array (
            'title' => esc_html__( 'Video Background', 'text-domain' ),
            'id' => self::PREFIX.'video-background',
            'fields' => array(
                array (
                    'id' => self::PREFIX . 'join_button_text',
                    'type' => 'text',
                    'name' => esc_html__( 'Join Button Text', 'text-domain' ),
                    'std' => 'Join Now',
                ),
                array (
                    'id' => self::PREFIX . 'heading',
                    'type' => 'text',
                    'name' => esc_html__( 'Heading', 'text-domain' ),
                    'std' => 'Grow your piano studio',
                ),
                array (
                    'id' => self::PREFIX . 'subheading',
                    'type' => 'textarea',
                    'name' => esc_html__( 'Sub Heading', 'text-domain' ),
                    'std' => 'Refresh your teaching, supercharge your business and feel supported every step of the way.',
                ),
                array (
                    'id' => self::PREFIX . 'play_video_button_text',
                    'type' => 'text',
                    'name' => esc_html__( 'Play Video Button Text', 'text-domain' ),
                    'std' => 'Play Video',
                ),
            ),
            'category' => self::CATEGORY,
            'render_template' => lpg_get_plugin_path().'blocks/video-background.php',
            //'enqueue_style' => lpg_get_plugin_path().'blocks/video-background.css',
            'icon' => 'video-alt2',
            'keywords' => array(
                0 => 'video',
                1 => 'background',
                2 => 'top',
                3 => 'header',
                4 => 'hero',
                5 => 'jumbotron',
            ),
            'supports' => array(
                'align'           => ['wide', 'full'],
                'customClassName' => true,
            ),
            'description' => 'Video Background',
            'type' => 'block',
            'multiple' => false,
            'enqueue_assets' => $this->load_gutenberg_styles('video-background'),
        );

        return $meta_boxes;
