I haven't tried (just installed Windows 10 v1909 last night) but I don't think so, given that WSL2 sits in a VM, which WSL1 didn't.

I liked WSL1, but it had a lot of the same drawbacks that Cygwin had, which was that Windows and Linux are different enough under the hood that you start running into issues with file system performance and containers, and WSL2 fixes that at the cost of being clumsier with file management.

The solution I recall for WSL2 is to put the shared files inside the Linux instance instead of putting it in NTFS.
