How to setup Horde Agent that's ONLY used as UBA helper (i.e. only compute tasks)?

So far, this is what I’ve done on some workstations:

  1. Install Unreal Toolbox on my own workstation
  2. Install Horde Agent from Unreal Toolbox, and set Agent mode to “Workstation” instead of “Dedicated”.

What I want to happen is to have my workstation only be used as a UBA “helper”, so it can be assigned compute tasks by the server/other dedicated agents.

However, currently my Workstation agent is treated like a regular agent in Horde and added to the same pool as other dedicated Windows agents. This causes the server to sometimes assign build jobs to my workstation agent, and it keeps trying to conform my workspace, which I don’t want to happen.

What’s the correct setup to have “Workstation” agents be setup to only help with compilation but not need to conform the whole project workspace?
