  There's a simple answer: don't add something if it's not needed.
Adding it and then deleted it is complicated, and prone to errors.

  Instead, add it *only* if it's necessary.  This may involve update the
LDAP maps to use a temporary attribute.  e.g. map the LDAP data to
"My-Chargeable-User-Identity", and then map that to
Chargeable-User-Identity only when necessary.

  See raddb/dictionary for how to define local attributes like this.
