Disable record auto-creation?

We have some automation in our environment which handles the
adding/removing of Foreman records for hosts as they are spun up. I've
noticed if a guest is spun up, and the Foreman record creation automation
fails initially, the record will be auto-created in Foreman after several
minutes time. The problem is when this record gets auto-created, it isn't
populated with some of the site-specific information our in house
automation puts into the host parameters.

I'd like to disable this behavior where the host gets auto-created by
Foreman, but I'm not sure where to do this. Can anyone point me in the
right direction?
