Clear cache without deduplication

[msmicker]

I have an app with relatively infrequent data updates - updates are usually coming from the currently logged in user. Still I enjoy using swr for ease of use and manage the current users changes through mutate operations without flagging for revalidation. I set deduplication globally to a high value (5 minutes) to avoid unnecessary calls to the backend.

I am looking to completely clear the swr cache when the user logs out, but am having trouble managing this through the undocumented cache feature. It works if I set deduplication to a low value, but my SWRconfig is currently at a top level in my app and does not get refreshed during login/logout (otherwise I might dynamically set config there based on login/logout).

Before I spend a lot of effort reworking something, I am just doing a sanity check. Is there a very easy way to fully clear the swr cache without changing config?
