Get CRM Partner URL in runtime

Summary:

Hi All,

The ask over here is to get the CRM Partner URL in CPQ within run time (BML).
Wanted to understand is there any attribute or function or API which can get me the current CRM Partner URL (CRM end point URL in the integration center)

Currently we have a CRM Connection to salesforce, so what we need is the CRM end point url Dynamically.
