Disabling Wireshark attempt to decrypt QUIC traffic

Since I have disabled encryption in a QUIC implementation, the interaction between the client and server takes place in plain text. However, Wireshark still attempts to decrypt the interaction and fails to dissect the plain text. I am wondering if there is a way to disable Wireshark's attempt to decrypt QUIC traffic.

Are you using a "standard" such as draft-banks-quic-disable-encryption-00 ?

The implementation ( does not support it. So, I just disable encryption/decryption functions.

There are open issues (Disable encryption #181, Disable encryption #483) on the h2o/quicly Github.
It would be better if they would follow something like the draft-banks-quic-disable-encryption-00 which might then be added to Wireshark.

Until then, there is a GQUIC preference (QUIC: Add preference to force decode all payload) that maybe could be duplicated in the QUIC dissector. Please open a Enhancement/Feature request on the Wireshark Gitlab Issues page.

(If you open a Feature Request, please add a link back to this question)
