Not able to make a static or html only site

I have been reading that you can setup a static site if you just make a Wordpress install, delete all the Wordpress files and then push it back up to FlyWheel but when I try this it always says in Local non Wordpress sites are not supported. I even tried to just pop in via sftp and delete the WP files but that doesn’t work either. Has this option been disabled or am I missing a trick? I mean I can always just leave the entire WP build in place but it seems sloppy.
