Yes. Access → Exclude. Tick a named place under Common exclusions, name a particular page under Excluded pages, or write an address with a under Excluded addresses — /contact/ leaves everything under /contact/ reachable. An address copied from the browser works too, letters from other alphabets included. While your page is up, the Dashboard tells you if a line there leaves your front page, or every page, open.
If Excluded addresses shows a line that is only /, // or //* that you did not mean, or a line missing some of its letters, delete it and paste the address again. Earlier versions saved an address in another alphabet or with an accent that way, and the first three leave the front page, or every page, open.
You can also cover only part of the site: Where it applies → Apply to → Shop and product pages covers the shop while the blog carries on.
