Sorry, I've no clue what you mean by "data privacy" in the context of reverse incremental. No matter which backup mode you use, the exact same data chunks will be stored on your repository hard drives and can therefore be exfiltrated (of whatever your data privacy concern is). The only difference will be in file structure organizing those chunks in the file system.
Actually, no: in case of forward incremental "rewriting" happens after VM snapshot has already been closed, which makes dramatic difference to VM lifetime and therefore impact on production VM.

for data privacy:
we have to delete some data from time to time, if we do en endless forward incremental, we have data back to day n.
so veeam has to take care and delete old data so we get n (oldest), n+1, n+2, n+3 (current) Backups.
After n is out of scope it has to be deleted so no data of n will retain.
we just are allowed to store from n+1 to current.
if we do reverse incremental, we just say store n, n-1, n-2, n-3 but never n-4.
