Are the url cache busting timestamps configurable?

[Renier Morales]

While using jupyter notebooks with extensions enabled, I've noticed url requests in the background like this:

../nbextensions/code_prettify/kernel_exec_on_cell.js?v=20191104122717

It seems a timestamp is added to the resource url being fetched for defeating any caching that may be going on (browser, proxy, etc.).

Is this configurable in any way? Can it be disabled?

Thanks,
