Primary disconnect for transformers

[JB78]

NEC 450.14 allows for transformer primary disconnects to be located remotely if they are "lockable". Is permanent add-on locking hardware for individual circuit breakers, installed by the (electrical) equipment manufacturer in an MDP, acceptable to meet code requirements?
Thank you.

IMO yes.
