Why is the terminal PowerShell by default? Can I use Cmd.exe, instead?

If I create create/open a PlatformIO project, the terminal is “powershell” by default. In my VS Code settings, I have set cmd.exe.

If I click “select default profile”, it shows the following but clicking “Command Prompt” does not seem to anything.

Why is this happening? How can I make it command prompt instead?
