Is it possible to track hidden class creation?

Hi there, Recently I've been trying to get rid of certain deoptimizations due to "wrong map" (--trace_deopt). However, there's a situation, when an object's properties remain the same, but the object map gets changed, which leads to deopt. So I was wondering is there a node's option to track those changes, or probably some internal V8 functions, that may give some information?
