Unfortunately not. In the
MA case they just lessen the amount of light that hits the sensor so you can have a longer exposure. On a variable aperture lens it also lets you shoot with a wider aperture thereby increasing your depth of field.
A circular polarizer can reduce glare but it has to be adjusted manually to get the best results. I'd imagine that's a lot of guesswork with a drone.
Keep in mind that anytime you introduce another layer of glass between the subject and the sensor you run the risk of introducing flaring.
