Disable inline styles on all pages

The plugin adds inline styles to all the pages of the website, Even if it doesn’t contain a CF7 form.
this ads unnecessary code that i want to remove on pages without a form.

i already has a script that checks for the CF7 shortcode:

add_action('wp_print_scripts', function () {
	global $post;
	if ( is_a( $post, 'WP_Post' ) && !has_shortcode( $post->post_content, 'contact-form-7') ) {
		wp_dequeue_script( 'google-recaptcha' );
		wp_dequeue_script( 'wpcf7-recaptcha' );
	}
});

i tried to add
wp_dequeue_script( 'cf7-material-design-inline' );
and
wp_dequeue_style( 'cf7-material-design-inline' );

but not of that worked.
