Captcha Script only on certain pages

Hi,

can i somehow archive it, to only load/start the google recaptcha on certain pages. Right now, the request is happening on very page.

I already have this code, but the google request is still happening.

add_action( 'wp_print_styles', 'aa_deregister_styles', 100 );
function aa_deregister_styles() {
    if ( ! is_page( array( 'katalog', 'kontakt' ) )  ) {
        wp_deregister_style( 'contact-form-7' );
		wp_deregister_script( 'contact-form-7' );
    }
}
