I'm sure it's fine, I actually had a post about this same issue with cage decor a few days ago. If it were me I'd wait till he comes out and then take the decor and fill up the really deep holes with aquarium sealant let it dry for 48-72 hours and then put it back. You want there to be places in the decor to hide but you also don't want to lose access to your snake when you may need it.
