How to give a file from different directories by one URI?

Question

Nginx

There are several directories with files on the server.
The client requests a file at a single address.
How do I set up nginx to look for the requested file in my few directories. Preferably in the order that I would like to define.
I broke all the legs with named locations and rewrites, but I could not achieve the desired behavior :(
Thank you.

location / {
    try_files $uri $uri/ /dir/$uri /dir2/$uri /dir3/$uri = 404;
}
