It's a bit of a mindshift change but essentially whenever you feel the urge to make such a tweak...you've strayed off the golden path & are attempt to do something the wrong way (in Talos world).

I came from k3s so was very used to the whole tweaks spiel too.

Where you do need a custom config pipe in patch commands, not modify the OS. i.e. any and all changes you're feeding in via API so that can be repeatably scripted. The Talos OS is immutable.

It's similar how you'd control a k8s cluster with kubectl...except you're doing that model at OS level. You control it by sending API commands no modifying settings in files. So you don't "tweak" anything. It's a bit of mindset shift I know
