Hey Narek,
The only real mechanism you have at your disposal is the pooling mechanisms (it looks like you have a Linux-UE5 & Win-UE5). How I’d separate this is have all your helpers annotated within a UBA specific pool, and have your primary build machines (the thing kicking off the build) specified as the main pool for your template. These machines will then initiate the build on your build farm (and then instigate a UBA distributed build through the other agents via the corresponding pool). Let me know if I’m not understanding your question properly.
Kind regards,
Julian
