Register using some Auto-KMS script, something like https://github.com/massgravel/Microsoft-Activation-Scripts might work, haven't checked in in a while.
You really don't have to do scorched earth and install linux. Just do a proper install of win 11 enterprise, with Rufus, and a few minutes disabling anything else you don't like. Also, use explorerpatcher https://github.com/valinet/ExplorerPatcher to fix various things like start menu, task bar, etc.
No ads, no Copilot AI, no search using bing, no telemetry, etc. etc. You can safely ignore all the doom and gloom about how windows is getting worse because if you remove all the crap its actually getting better.
In the past 3 years, I think i've only had to occasionally do an update to explorerpatcher; everything else has stayed the same. they don't ever overwrite group policy changes and such.
