Set VS Code auto format to use tabs and not spaces?

1

Is there a way to configure VS Code’s Format Document and Format Selection commands to use tabs and not spaces?

Despite these options:

"editor.insertSpaces": false,
"C_Cpp.clang_format_fallbackStyle": "{ BasedOnStyle: Google, IndentWidth: 4, UseTab: Always, ColumnLimit: 0 }",
"editor.detectIndentation": false

are configured in settings.json auto format still converts tabs to spaces :-/
