I'm struggling to remember why we didn't do this originally, I suspect the option wasn't available on the daprd process in the early days but I can see it is now. You're welcome to submit a PR to resolve it, if not we'll get to it with the next round of changes. In the meantime can you outline the problem having metrics enabled is causing you?

If I find the time to create a PR before you guys, I let you know.

We are running multiple dapr sidecars on the same windows machine. Sidekick automatically tries to find a free port if the default is blocked. However, our python process' sidecar does not, which caused port conflicts and prevented the sidecar from starting.
At the moment we do not use the metrics, that's why I wanted to turn it off.

For our situation, it was enough to turn it off for the python process, but I also wanted to do this for .NET.
