Remove skip link from some pages

There’s nothing built in to do this, but there are a few things you could conceivably do.

If the pages with no navigation have a unique body class, e.g. ‘landing-page’, or something like that, you could just hide it using CSS on those pages. E.g.

.landing-page .a11y-toolbar { display: none; }

Other options are trickier; you’d need to filter the asl_enable option in PHP, to turn it off dynamically. But I’d expect that your landing pages should have a unique class that would allow you to use CSS. Looking at the page you shared, it seems to have the class .e-landing-page-template, and that should be something you can use.
