Is dcut.profile the right way to do it?

You can use the #duct/include reader

BTW, I'm trying this module https://github.com/kakao/duct-lacinia and I want put GraphQL's scheme in another file

@UG9U7TPDZ will try, thx

You can check example how to use #duct/include here https://github.com/khmelevskii/duct-pedestal-reitit/blob/master/resources/duct_pedestal_reitit/config.edn#L28. I put migration config to separate file
