Box Shield replacement for Content Security Policy?

Hi,

We have two upload policies created with Box Content Security Policy.  Now Box support is telling us Box Content Security policy is outdated and we should use Box Shield instead.

How do I create a policy in Box Shield to quarantine  Zip, Tar, Rar, 7z, and iso file types that users might upload?

I can't find where I can create upload policies in Box Shield.

Thanks,
