Funnel Pages in the sitemap?

Hey Community. Quick question: Does it make sense to have links, that are generated by a funnel builder in the sitemap?

The only purpose of these pages would be to convert cold traffic (coming from Informational articles) to email subscribers and sell them products on the backend.

I'm thinking of removing these /funnel/... pages from the sitemap, because I found out that pages mit Headlines like "SP - Product Name" are indexed.

So should I delete all these indexed pages (created by the funnel software), from the sitemap?

Thanks in advance 🙏
