We already described the generic case where security is applied (section
2.6), when the user plane emits the packet to transport (could be N3/N9
interfaces or S1U interface terminating at SGWs).
That addresses mostly shared transport cases.
If I understand correctly, you want security done by PE's before gNB/UPF??
I can imagine few usef of this but can you explain why you are looking for
this option?

Sure. But is this a mandatory option for your E2E use case with
SD-WAN beyond mobility domain?
