Couldn’t find it in either myself. Good to knowPage 7 in the Matrice M30 Maintenance Manual.
I called DJI tech support when I couldn't find any recommendations about prop replacement in my Air 2S or Mavic 3 manuals. They told me it was recommended to replace at 300 hours or sooner if the drone was flown hard (sport mode, fast starts and stops) or at high elevations.
When I bought my Matrice M30, I found the actual maintenance information recommended by DJI there.
