Setting up trpc behind AWS API gateway and authorizing using a lambda

Current setup:
- trpc api, containing both public an private procedures. Let's call them 
posts.list
 (public) 
posts.create
 (private)

- API gateway routes 
GET /trpc/{proxy+}
 and 
POST /trpc/{proxy+}
 that invoke a lambda handler for trpc (let's call it 
trpc.handler
)

- Auth is handled inside of 
trpc.handler
 using a middleware that checks the token etc.

Setup I want:

- Extract the auth part into a different lambda (let's call it 
auth.handler
)
- Only run this authorizer for the private routes.

As I don't know in advance what the request url might look like (e.g. it could be batched), is this possible to setup?
