Disable the_content hook

Hello. Please tell me how to turn off the filter ‘the_content’ via theme’s functions.php?

class StructuredContent_Shortcodes {
...
private function __construct() {

		$this->_version = STRUCTURED_CONTENT_VERSION;
		$this->_slug    = 'structured-content';
		$this->_url     = untrailingslashit( plugins_url( '/', dirname( __FILE__ ) ) );

		add_shortcode( 'sc_fs_faq', array( $this, 'faq' ) );
		add_shortcode( 'sc_fs_multi_faq', array( $this, 'multi_faq' ) );
		add_shortcode( 'sc_fs_job', array( $this, 'job' ) );
		add_shortcode( 'sc_fs_event', array( $this, 'event' ) );
		add_shortcode( 'sc_fs_person', array( $this, 'person' ) );
		add_shortcode( 'sc_fs_course', array( $this, 'course' ) );
		add_shortcode( 'sc_fs_local_business', array( $this, 'local_business' ) );

		add_filter( 'the_content', array( $this, 'fix_shortcodes' ) );
		add_filter( 'category_description', array( $this, 'fix_shortcodes' ) );
	}
...

public static function register() {
		if ( null === self::$instance ) {
			self::$instance = new StructuredContent_Shortcodes();
		}
	}
...
public function fix_shortcodes( $content ) {
		$array   = array(
			'<p>['    => '[',
			']</p>'   => ']',
			']<br />' => ']',
		);
		$content = strtr( $content, $array );

		return $content;
	}
...
}

StructuredContent_Shortcodes::register();

Sometimes my content starts with <p>[my_custom_shortcode] … and the plugin cuts out the paragraph tag etc.
