Cache with TRPC app router

Hi guys, I'm struggling implementing cache in my nextjs app. I'm using nextjs with TRPC and app router and it seems that both server and client calls to my TRPC routes are in "no-cache" mode.

Have you got any good ressources to change that ? (relevant repository for example)
I want some query to be cached and some not, and maybe implement a full router cached... If someone can help
