With the example file I used (a batch script with a lot of sections) I saw that when I selected the Py scheme as the syntax scheme for this file, code folding options appeared.
With its basic structure, only the YAML, Visual Basic, VB Script, Cmake Script and AutoIt3 syntax schemes showed somewhat similar code folding options, so you likely could use any one of these.
Then I manually indented (4 spaces for each indentation) the content of this file...same set of syntax schemes do code folding.
Replaced all spaced indentations with tabbed indentations and again only the same set of syntax schemes do code folding.
I think it is safe to say that the code folding functionality doesn't respond to the use of tabs or spaces. None of the code folding in the other schemes matches the code folding from the Python syntax scheme, though.
To me it means that there are 3 main solutions to your question.
1. Do the cloning solution you mentioned in your last post in this thread.
2. Adjust the rules of the code folding functionality that is there.
3. Use different software.
For this small test I used
Notepad2-mod 4.2.25.870 (64-bit zip).
