Actually you don't need to do this.

True - however, the component used here should allow the secure connection on port 8883.

The config passed to the esp_mqtt_connect needs some slight changes (the verification key needs to be set, and the broker address needs to change to connect to the secure port) - I'm hoping this will prove to be straightforward (famous last words?))

Here it connects securely.

The hard part was finding the correct certificate (in the end I downloaded from DigiCert)

The code also needs to get the current time - which it does using the SNTP component.

As before - needs channel, password, username and SSID details..
