Using Paho 2.+ Python MQTT with TPM [message #1872566]

In our project we need to secure the MQTT communication with Trusted Plattform Module.
The paho script for a MQTT communication with a Iot broker is working, but with TPM is failing.
Meaning error like:
Setting of the TLS connection failed. Exception = [SSL] PEM lib (_ssl.c:3916)

are popping up.
No connection with a device certificate generated from a plocal private key (generated with TPM).

Questions:
1) is paho even capabel to handle TPM backed connections ?

2) If yes what is general workflow for accopmlishing that?
