How to Delete existing Constraint on a Soft type attribute

Hello All,

I am trying to delete an existing constraint on a soft type attribute. I dont want to do it manually from "Type & attribute Manager" console. I need to propogate changes on different environments. So, I am looking for any OOTB methods / xml templates using which I can upload the xml file and update the attributes.

Using thishandler="com.ptc.core.meta.type.mgmt.server.impl.TypeDefinitionNodeLoader.beginUpdateTypeDefinitionNode to update and add new constraints.

I am able to add new constraints to the existing soft attributes but not able to delete.

Any suggestions on this topic is very helpful..

Thank you.
