Modify a definition query of a feature service after publishing to ArcGIS Server

[Col_Forbin]

I published a feature class to ArcGIS Server 10.7.1 from ArcMap that had a definition query.  The service seems to be respecting the definition query just fine.  But now I'd like to modify the definition query.  Is there any way to modify it after it has been published?  Or can I at least see the syntax so that I can overwrite the service?

Expand the Feature that you want to update and there is a button called Filter which is the same as the definition query you set up.

Is this in the Server Manager?
