Does Using dynamic functions on Root Layout makes the whole app dynamically rendered?

[jovanhartono]

as described on https://nextjs.org/docs/app/building-your-application/rendering/server-components#dynamic-functions
does invoking cookies() on root layout makes the whole app dynamic?
i see the implementation on the vercel commerce app https://github.com/vercel/commerce/blob/main/app/layout.tsx#L40

thanks!
