The Windows drivers for ext4 can be flaky, especially for writing data. I’ve seen them used more for reading data off a drive. However, I think since v2021 Windows opened up ext4 access by mounting via the Windows Subsystem for Linux 2 using a specialized WSL mount command. I have not tried it, but, if you want to this should help.
I still think a simple external USB drive is always the best option for a NUC (or Nucleus) for a variety of reasons.
Since, what you are asking for and trying to do is outside the parameters of normal usage, I am moving this to the Tinkering section.
