There is no way to physically drag the handles in the same way at the same time. But for basic handle movements you can achieve the same (or similar) thing. In the Spline Editor you can press T to bring up the ease in/ease out controls, and/or use the Ease context menu to apply various pre-defined easing curves to a number of keyframe pairs at once. That Ease menu also has a Dialog option with some basic control of the curve shape.
I made a mini-tutorial the other day that covers adjusting easing for multiple sets of keyframes (on different parameters - in this example, Transform Y & Transform Size) at the same time, to ensure the parameters remain in sync. It also briefly covers modifiers and expressions for doing the same thing.
The tutorial was made for someone who hadn't used Fusion before, so it might be a bit basic at the start.
(apologies for audio quality, I made it quickly using a crappy mic)
