PVC adds css code to header, with no option to turn off

[kospl]

This is CSS output added on each page:

		<style>
			#wp-admin-bar-pvc-post-views .pvc-graph-container { padding-top: 6px; padding-bottom: 6px; position: relative; display: block; height: 100%; box-sizing: border-box; }
			#wp-admin-bar-pvc-post-views .pvc-line-graph {
				display: inline-block;
				width: 1px;
				margin-right: 1px;
				background-color: #ccc;
				vertical-align: baseline;
			}
			#wp-admin-bar-pvc-post-views .pvc-line-graph:hover { background-color: #eee; }
			#wp-admin-bar-pvc-post-views .pvc-line-graph-0 { height: 1% }

		</style>

Followed this guide: https://dfactory.eu/support/topic/exclude-stylesheet-when-not-displaying-counter-on-front-end/#post-36689

add_filter( 'pvc_enqueue_styles', '__return_false' );

It removes dashicons and frontend css file, but mentioned above inline css is still output on the page.
