Hi,
have you seen this?

Personally, in my game I try not to use colliders either.
I have code like this:

GraphUpdateObject graphUpdateObject = new GraphUpdateObject(bounds);
            
graphUpdateObject.updatePhysics = true;
graphUpdateObject.modifyWalkability = true;
graphUpdateObject.setWalkability = false;
AstarPath.active.UpdateGraphs(graphUpdateObject);

and it works for me. The only problem is LayeredGridGraph and paths that are above or under another path/blockade. For that I need to use basic colliders.
