Qualcommax NSS Build

I hope this is now gone with merging of the PR.

I have a question about VPNs.
I 've setup a WireGuard connection to a VPN provider (there is OpenVPN support too) in order to be able to expand the versatility of my whole network along with the amazing Policy-Based-Routing PBR package.
With WireGuard I get above 400 Mbps (1G ISP line) which is great but in that case of course the CPU usage is high as the WG connection is not NSS accelerated.
So my question is following.
Is/Are there a security protocol/s (IPSec, OpenVPN) that are (or can be) NSS accelerated.
Has anyone tried the options - Enable IPSEC and/or Enable OpenVpn (QVPN).
