Foreman

Is it possible to limit the host provision (build) process to only create the pxe configuration file (based on mac address) on the (remote) tftp proxy server?

I'm currently getting the pxe config file created on the remote pxe server but then foreman continues the tftp host provisioning process on what appears to be the foreman server, where I don't have a tftp server running.

Here's the error I'm getting from foreman:
