To make your life easier, it's better to use a separate router to handle
your new subnets.
So you don't need to change anything on your AD DC.
BTW, you have to have a router to do the routing.
I have a router, and the router will route the connections bewtween hosts in differents subnets, but I want avoid latency introduced by routing when clients try to reach files in the File Server. I can attach a interface for every subnet in the File Server and I want use this interfaces for direct access. I don't know if it is possible (May be pushing a route into the hosts using a GPO...?)

What is the use of "subnets" in "Active Directory Sites and Services". AFIK Samba supports sites, and Microsoft's docs  tell about sites with routed subnets and so on. Why "N/A"?

You have to do routing between subnets either via a router or your AD DC.
I don't think it's a good idea using the AD DC as a router.
Does routing affect the file sharing?
