I think the only way to do this is in Python via hou.AgentDefinition
If there is a good use case for this please RFE adding it to the Agent Clip SOP. I haven't come across many use cases for needing to do this, especially since the clip library is delay-loaded from disk.

The default behaviour is to compute the COM on the first simulation frame, so you probably need to turn off Compute Center of Mass (the 'computecom' point attribute)

Can you attach an example of your HDA? This approach should work for letting a custom HDA act as a trigger
