I can't speak for DJGPP here, but presumably the answer is no. Even
the alleged 4 GB-1 support (in 2.04) was seemingly never tested much.
I don't think NTVDM ever supported that, only Win95 (OSR2.5 or
whatever). Besides, I think Win10 requires a late-model P4, thus
presumably everything newer will be 64-bit only (similarly like new
WSL is). So it may all be in vain.

There recently was a guy working on some exFAT user-land tools
(written in C) for FreeDOS (a la LTOOLS). He wasn't nearly finished
with it (last September), but maybe he's farther along by now.
Honestly, I somewhat advised him against it (after the fact, in lieu
of ext2) because of the patented nature of the mess, but he didn't
seem too phased by it. He seems very open to outside testing and
contributions, so do feel free to email him if you're that curious.

P.S. I haven't tried rebuilding libc in years. I remember that FreeDOS
had a NUL bug that I reported to them for you, but they've never
released a newer (official) kernel yet, though some backlogged commits
were done to SVN two months ago. So I haven't tested the NUL fix
itself, but I did get very close to trying it (under VM) in the past
week or two. If someone wants to test that, I can offer some advice.
It should honestly be quite easy (famous last words)! Even though
FreeDOS overall is anemic (at best), I think it's a better (long-term)
target than Windows is these days.
