How to change gravity?

Hello!
I want to turn on Gravity simulation for an actor (cube), when the player overlap a trigger box.
Without overlapping the trigger box, actor (cube) will remain without gravity simulation.
How can I achieve it through blueprints? Is there a node to turn off/on gravity for actors?

I want to make a scene; when character overlapp a trigger and one object start flying around. Same as if would manually turn on gravaty for actor.

Thank you. I will try

So you still want physics interaction but no gravity?
