Excluding SEO from an entire route via _layout page?

[epitaphmike]

It seems like one can include SEO at the _layout route page, but doesn't seem like it can be excluded.

For example. If I add
export const handle: SEOHandle = { getSitemapEntries: () => null, }
on a _layout under /admin+, all the pages under /admin/* still show up on the sitemap.
