Yes.

I tested kmod with Python 3 outside of Buildroot and it works fine.

However, with Buildroot there is a problem because Buildroot generates a
Python 3 installation that does not follow PEP 3147 "PYC Repository
Directories". This means that *.py[co] files are not installed in
__pycache__ directories and this makes python-kmod fail. But this is
problem with Buildroot's Python 3 installation. There is no issue with
Kmod here.

Thanks!
