Are you referring to processing 0-RTT HTTP/3 requests?
Anyway, please try this change and report back.

QUIC: speeding up processing 0-RTT.
After fe919fd63b0b, processing 0-RTT was postponed until after handshake
completion (typically seen as 2-RTT), including both ssl_ocsp on and off.
This change allows to start OCSP checks with reused SSL handshakes,
which eliminates 1 additional RTT allowing to process 0-RTT as expected.
