Where is the trigger to execute this script with enable/disable option? Is this part of pmon?

There is no trigger for this script, this is just a utility script which would be helpful for enabling DPU traffic to reach the internet in cases where connectivity is required, Example Usage:
SONiC to SONiC upgrade on the dpu can be performed easily if we enable DPU management traffic forwarding using this script, as the DPU can download the image directly, instead of first transferring the image to switch and then to DPU
[SmartSwitch] DPU Management Traffic Forwarding script
Why I did it
This script is added in order to enable or disable the management traffic generated from DPUs to be forwarded through the smartswitch. When we enable the traffic the following actions are taken:
bridge-midplaneinterface) to the management port on the switch -eth0eth0to the DPU (connected to thebridge-midplaneinterface) for established or related connectionsThe opposite actions are taken when we disable the traffic
