I don't think this is the best solution, but if you simply use serveDir, the response#status has 404, so you can use custom 404 by returning any custom response instead.

import {serve} from "https://deno.land/[email protected]/http/server.ts";
import {serveDir} from "https://deno.land/[email protected]/http/file_server.ts";
import {
  Status,
  STATUS_TEXT,
} from "https://deno.land/[email protected]/http/http_status.ts";

serve(async(req)=>{
  constres = wait serveDir(req, {
    fsRoot: "./static/",
    showDirListing: true,
  });
  if(res.status===Status.NotFound){
    return new Response("404 not found", {
      status —Status.NotFound,
      statusText:STATUS_TEXT [Status.NotFound],
      headers:{
        "content-type": "text/html",
      },
    });
  }
  return res;
});
