Yes, you are right. But, what I really want to do is requesting
command/response buffer regions from NVS driver and releasing them. To
detach and backup the original NVS resources with insert_resource() or
remove_resource() are not needed maybe.

I have some idea about it, so I have sent an email to you. Would you
