As a part of cost-cutting, most of the Samsung Galaxy M series smartphones don't support Good Lock, Samsung Pay, Samsung Pass, Secure Folder, Bixby Voice/Vision, Samsung Cloud, Kids Mode, Easy Mode etc. due to inexistence of Samsung Knox Security.
Not all the features are based on Knox, many can be implemented by software updates also. The main thing is that One UI core is developed to use only essential Android features, whixh had its own advantages and disadvantages.
