Yes but an HTML file is very different from a website. At the very least I’d like an option to disable all remote requests, or disable previews for certain file formats.

I did this a few months ago, Bazzite makes it extremely easy. Just install Bazzite, and during the initial setup, there is a toggle to enable “Sunshine”, and it will automatically install everything necessary. Afterwards install the Moonlight client on any other device, and connect to your Bazzite PC from within Moonlight. Official docs for Sunshine are here.

To uninstall, you can just re-launch the Bazzite setup wizard, look for “Bazzite Portal” in the desktop menu. If you want, you can also install/uninstall Sunshine from the terminal, run sudo ujust setup-sunshine.

Note that for Sunshine to work you will need to either have a monitor plugged in, or a dummy HDMI dummy adapter.

I remember at some point I had some issue getting Sunshine to auto-start after booting the PC. I think what I did was enable auto-login, so that once the PC booted it automatically logged into the default user, without asking for password or anything. This is pretty insecure so only do this if you can’t find another way. You can also manually start the Sunshine service by ssh-ing into the PC and doing systemctl --user start sunshine.
