Win 11 IoT Enterprise LTSC is what you want. It comes with a grand total of zero drivers, so you’ll need to download them to a USB drive before installing, otherwise you won’t even be able to get online because there’s no driver for the ethernet or WiFi. You can even uninstall Edge! (Which you should definitely do.) I think that massgrave.dev is considered reputable for downloading and activating, which is done by shell scripts. You should be able to turn off pretty much all telemetry on it.
