NRF9160 / Asset Tracker V2 / AWS - Power consumption problem with MQTT_KEEPALIVE

Question

I have an application modified from the Asset Tracker V2. It is on the 1.8 SDK. 
 I am able to get the power consumption low, but every 20 minutes the application starts the modem and pings AWS. This is because of: 
 
 # Maximum specified MQTT keepalive timeout for AWS IoT is 1200 seconds. 
 #CONFIG_MQTT_KEEPALIVE=1200

The Asset Tracker V2 code does not disconnect from AWS until the modem is shutdown, but in PSM mode- it will not shutdown (and therefore send a shutdown event). 
 
 What is the easiest way to stop these connections? 
 
 Thanks

Please note that t he Asset Tracker v2 is a real-time configurable ultra-low power capable application. This does not mean that it is by default configured to lowest possible configuration. The application is a demonstration of what our nRF9160 is capable of, but will not reflect all use cases.
