This might be possible, but I do not know the exact end-point you should use. You can for instance see the load status of a Data Model via the Celonis API as described in the PyCelonis Docs:
Yes, I don't know if this is the best way for this goal, but you can configure a skill which simply reloads a data model. Then I believe you'd setup an action flow only with the execute automation skill module (which you link to the aforementioned skill)
