Rui Wang Dec. 14, 2025, 6:16 p.m. UTC 
Split the prepare() function into prepareDisabledMode() and
prepareEnabledMode() to improve readability and maintainability.

This separates the logic for disabling and enabling the DPF, making
the main prepare() function cleaner and easier to follow.

changelog :
 - Add blank line into code
 - removing  frameContext.dpf.denoise = false in prepareDisabledMode
