[strongSwan] ikev2 - configuration payload in spite of explicit virtual IP address

An IP specified with leftsourceip is always requested via a
configuration payload in IKEv2, even if it is fixed. If you don't want
this, just omit the leftsourceip parameter.

Of course you'll have to make sure your source IP is in the negotiated
tunnel, e.g. by settings leftsubnet=192.168.10.20/32. Also, the IP
address is not installed by the daemon.
