vmware Photon OS 3.0 Customization

I am trying to customize the photon os 3.0 ova as same as guest customization which is done on windows or linux vm.

Here is the requirement. Is something possible to script it?

1. We ship  photon ova to the customers for building docker containers.
2. Once we ship this to customers they will deploy the ova in vcenter cluster by passing all required parameters from a variable or a json file(hostname,ip etc)
3. Objective is to have all the configuration parameters in a json file and use import-vapp with OvfConfiguration passed from that json file.
4. After deploying ova using invoke-vmscript and we need to push the code to install docker & other container application
