How to block a VS Code extension from opening output window on every parse error

When using Microsoft's Kubernetes extension in Visual Studio Code, the output window pops up every time there's a Helm parsing error. This is visually disruptive.

How can I prevent the output window from opening on parse errors while keeping the extension enabled?

Unfortunately, I haven't found a way to disable output window pop - neither in VS Code's general editor settings nor the Kubernetes extensions. Have I missed something?

Here's a screenshot to show what I mean by "Output window":

Update: An issue tracker search reveals there appears to be no solution at this point and others share the pain. #1137 #1100 #929 #907

There's a community PR open to fix it: https://github.com/vscode-kubernetes-tools/vscode-kubernetes-tools/pull/1208

Unless the extension provides a setting to disable it from doing that, you're out of luck.

There is the workbench.view.showQuietly setting from the November 2024 release, but that will affect the output panel for all channels, regardless of which extension is writing messages to them. You'd use that like this:

"workbench.view.showQuietly": {
    "workbench.panel.output": true
}
