I believe this can be done without a MitM by using Wireshark or adjacent tool
It's possible, but not easy. You need to export the internal state of your TLS stack to Wireshark in order for it to decrypt the traffic. This can be done via LD_PRELOAD type shenanigans but it's difficult and fragile.
MITM proxy is much easier to get working.
