There's a 'NTVDMx64' project which I've heard can get the 16-bit DOS VDM working in a 64-bit edition of Windows.  I haven't gotten it fully working though, and I think it may be a bit finnicky, especially on Windows 11.

I eventually decided to move my BBS to a 64-bit Linux distro.  16-bit DOS doors run decently well with dosemu or dosemu2 (at least with Synchronet).
