Am using GKE(google managed kubernetes) and I have requirement where I want to leave around 10% of memory on each Node as Idle so that during burst workload scenarios, the pod's already deployed on that Node can make use of those idle resources (within limit range)

Basically What I want to achieve is, I want to avoid a scenario where Pod's get scheduled onto a Node till 100% resources are consumed and assuming all the Pod's/Services are utilizing their allocated resources (set via requests) and one of the POD has a burst workload scenario or the pod got restarted and it needs more memory during boot up, then it should be able to make use of those idle resources

After going through the documentation I have come across this, but since GKE is a managed service, these properties aren't exposed anywhere, are there any other ways to achieve the same ?
