Using AI Fabric endpoint for projects on internal orchestrator

I am wondering how we can publish a project that uses an ML Skill endpoint for processing invoices on a process within our own internal orchestrator.

We have many jobs/environments/robots/etc set up in orchestrator installed in our system. We do not use the Clout.uipath.com orchestrator. How can we set up AI Fabric endpoints and use them in projects deployed in our environment?
