I haven't used it, but it might be that vmod can do it for you?

std.cache_req_body(32MB);

https://www.varnish-cache.org/docs/trunk/reference/vmod_std.generated.html#func-cache-req-body

The docs say:

"Caching the req.body makes it possible to retry pass operations (POST,
PUT)."

So it seems you can only use it for restarting/retrying requests, but
you can always give it a try.
