Welcome! :bigwave:

Can you clarify your question? Are you asking for examples or are you unsure of why only a design/process revision (to eliminate the function) can change the severity?

Manufacturing process design change can change the severity of a process function but it cannot change the severity of a product design function...

A process design change may reduce the Occurrence rating, but not the Severity rating for a product failure mode.
