Komodo will have a NNUE engine soon:

Komodo 14.1 Release and Dragon Announcement
http://talkchess.com/forum3/viewtopic.php?f=2&t=75651
"... [Dragon by Komodo] which is now playing in the chess.com CCC
tournament as "Mystery" and which we expect to release soon. It uses the new NNUE technology that was
developed for the game of shogi, but not the NNUE code. The search is Komodo search (with some parameters
tuned), and the nets we use are all trained on Komodo games and Komodo evals. The net is embedded so the
user need not do anything special to use it (though it can be turned off).
...
Special thanks to Dietrich Kappe for his expertise in training the nets, to Dmitry Pervov of chess.com
for writing the NNUE code we use and for many other enhancements to Dragon,

A short test Dragon NNUE. You still have problems with time, unfortunately the same bug is in Komodo.
{with a link to Test Komodo NNUE.pgn}

Results: G/5'+3", 3 move openings
not reversed, alternating colors,

Dragon NNUE x64 +1 =8 -1  5.0/10

Here using the same TC and openings

My last post this thread: Komodo 13.3 took 6 seconds to find 54...Qh5(!), on my 14 Ryzen threads not the 90 threads (6.4 times more) at CCC.

54.d5 is not 'just a pawn move' it is also a 'discovered protection' allowing white's B to protect against black's threat of ...Rf2-b2+ which would be bad of course because black's Q could then join the attack, Ka4 ...Qb3#.

In the diagram white's Q is protecting b2, so 54.d5 also 'unleases' the Q.

Still early, Dragon by Komodo is now a half point ahead of Stockfish Classic.
Dragon has lost only 1 game so far, the one in my last post.
