HMR can't be disabled (hmr: false)

[arpowers]

Describe the bug

I believe that HMR should be disabled if it is set as hmr: false and/or vite is running in production mode.

This is an issue in my case, as we'd like to just run the dev server for a testing site but we get these continual pings (noise)

here is the example site:Example Site

config has this:

const viteServer = await createServer({ 
      mode: "production",
      server: {
        middlewareMode: true,
        hmr: false,
      },
      appType: "custom",
       // other config
    })

Note that I've seen others comment about the lack of ability to turn off HMR elsewhere since the 3.0 release: example

The websocket is used for more than HMR as explained at https://github.com/vitejs/vite/issues/6315#issuecomment-1166558944. Disabling it completely would disable the other features too. Maybe we can allow that, but it would be good if you're proxying the websocket server too.

Thanks. As an idea, I think that with transpilation becoming less of a problem Vite could run SSR directly from the DevServer instead of the dual-build (very complicated) SSR method currently recommended.

We ran into a few small issues doing this (like the above) but it almost worked. Feels like a missed opportunity.

I'll close this for now as it's working as intended.
