Not sure if this video might provide any ideas, cuz an energetic puppy in his chewing stage who is home alone IS an energetic puppy in his chewing stage home alone....
but, for whatever it is worth, this quickie video *might* help, or it might not, but, it can't hurt.
My pal whose dog is eating his vertical blinds, used this to get his puppy happy to be home alone in a dog-proofed bathroom full of kongs and puzzles, etc. (of course, no way to remove a cabinet from a bathroom...
but, you could put bitter spray on the cabinet )
but some dogs do better not shut into a room, but my pal wants his dog shut into a room cuz he is so upset about alllll the blinds in his home are destroyed.
