configurable lease section timers?

hi, 
it seems the CSI lease timers are all hard coded,  could that be enhanced as configurable? 
in case it's used in some slow environment, as other lease? like kube-scheduler/kube-controller-manager

defaultLeaseDuration = 15 * time.Second
defaultRenewDeadline = 10 * time.Second
defaultRetryPeriod   = 5 * time.Second

thanks,
