Ah I see.
Another way might be to create a PhysX flow of your particles, attract them to the surface with a surface force and get them to a frame where you like how they look (by that point they should be hugging the surface and properly colliding with each other).
Then make a 2nd flow and use a Birth Flow operator to import the result of the first flow as an initial state of the 2nd flow. From there they don't need to be PhysX particles anymore...but you'll be starting with a visually pleasing state.
But maybe a simple surface align is enough for your purposes.
