You can't with the actual state of code in GDAL. This is purely a GDAL behaviour. Currently GDAL has a global 16 MB cache for all /vsicurl/ URLs: 1000 blocks of 16 KB each, with a least recently used eviction strategy. So yes it assumes static content. With some extra code we could imagine to evict with an option the blocks for a /vsicurl/ URL when the file descriptor is closed for example.
