Redfish and Remote File shares (RFS)

I'm converting an server build script that my team runs on CentOS linux from using racadm commands to using the Redfish REST API.   

We install the OS on servers using a customized CentOS boot ISO accessible from a Windows ( Samba) share. I cannot find the Redfish endpoint to do these tasks 

1) Attach the Remote file share (RFS) to the iDRAC 

2) Make the Remote file share (RFS) the next / one time boot device. 

I've scoured Dells Redfish repos on github but cannot find any code that works with remote file shares,

* https://github.com/dell/iDRAC-Redfish-Scripting

I don't mind using the Ansible Redfish module or the REST API for these tasks, so either way will work.
