Is it possible to add a flat network to a Fuel 9 deployed environment?

I have used Fuel 9 to have a successfully deployed environment with 3 Controllers, 9 Compute, and 3 Stacklight monitoring nodes.

I have a use case to have a flat network added to this environment and hope to use the bond0 for this purpose as well as have bond0 used for the originally deployed networking. Is this possible? If so can anybody point me to documentation that might exists for this?
