Not sure what you mean by that, M x V. In level flight thrust overcomes all parts of drag. In the glide thrust overcomes none of the drag. This does not alter the drag at a given speed and angle of attack. Lift to drag ratio doesn't incorporate thrust, just lift and drag, so lack of thrust will certainly not affect the lift to drag ratio at a constant angle of attack.
