Optimizer removes style.css version

I have a bit of code that adds a version number to the style sheet so that the user gets the most recent version.

wp_enqueue_style(
	'wsdg-responsive-style',
	get_stylesheet_directory_uri() . '/style.css',
	array(),
	filemtime( get_stylesheet_directory() . '/style.css' )
	);

With that working the link to the stylesheet is:
https://www.nevadacitychamber.com/wp-content/themes/wsdg_responsive/style.css?ver=1627584286

When the Optimizer plugin is activated, it changes to:
https://www.nevadacitychamber.com/wp-content/themes/wsdg_responsive/style.css

Any way to disable that?
