You can do this in Arcade

var arr = Split($feature.Field_Name, ',')
if (Count(arr) < 3) return $feature.Field_Name;
return Concatenate([arr[0], arr[1], arr[2]], ',');

You should mention what you're working in when posting a question.

This Python script will do what you want

def Calc(field):
  arr = field.split(",")
  if (len(arr) < 3):
    return field 
  else:
    return ",".join(arr)
