No. This setsockopt() works on the SOL_IP level, where 17 stands for
The call installs a bypass IPsec policy for the IKE socket, forcing all
IKE communication to stay outside of any established IPsec tunnel.

As already said, most likely is that your kernel (configuration) misses
support for XFRM. If that doesn't help, you might have to dig into the
kernel source and find out where and why Linux returns "not supported"
for this setsockopt operation.
