NGINX has an experimental QUIC branch [1], but in my experience it is buggy and currently has lower throughput than using Quiche [2] with NGINX. I do the latter for my fork of NGINX called Zestginx [3], which supports HTTP/3 amongst a bunch of other features.
NGINX's QUIC implementation seems to also lack support for QUIC and or HTTP/3 features (such as Adaptive Reordering Thresholds and marking large frames instead of closing the connection).
EDIT: A friend of mine who works at VK ("the Russian Facebook") informed me that they're helping out with the NGINX QUIC implementation which is nice to hear, as having a company backing such work does solidify the route a little.
