How to avoid caching for specific Nextjs API route?

Question

I have nextjs api route /api/auth/signout, it basically just clears the specific cookie and send JSON back.

The problem is, when I deploy project in Vercel, this particular API working first time properly (cookie cleared and giving 200 response) but later it's not working (cookie not cleared and giving 304 response).

I want to know, is there any way to avoid cache only for this route?

What's the best possible way to fix this problem?

Had a very similar problem with a corn API route and fixed it with

export const revalidate = 0;

in the route.js file
