Question Starting objects in sleep

Using havok physics, I'd like to have all physics bodies start in sleep. This is because I want to stack an incredible amount of rigid bodies and upon playing, move slightly and expose holes. The only way I can remedy is is by increasing the solver amount, at the expense of a ridiculous amount of lag. How do I start these physics bodies in sleep? I'm new to this whole ecs and dots thing. Help is appreciated.

 

I have found a solution! Just simply settings gravity to zero instantly puts all my objects to sleep, then when I set the gravity back, everything is all set.
