Can we set any filter for Workflow.

So if we update Name of HCP then only Workflow will be generated otherwise workflow will not generate.

Please suggest.

You can use Role Based Access Control to restrict permissions on the Name field so that it is only editable via Suggest mode - but this will not automatically push that change through a DCR - it will just enforce that a user leverage this option when editing this field.  In pure edit mode, the field will appear read-only, in Suggesting mode, it will accept proposed changes.  

Via the API you will need to manually add the alwaysCreateDCR=true option to the URL as documented here:
