You mean this? It's read-only and depends on environment.

The navigator.hardwareConcurrency read-only property returns the number of logical processors available to run threads on the user's computer.

The hardwareConcurrency and languages of the browser started using playwright do not match those of the actual system. They seem to be fixed settings. You can try to modify these two properties of navigator using javascript. It can take effect in the chrome environment, but the browser started using playwright does not matter whether it is chromium or not. Still in Firefox, these two properties cannot be modified successfully.
