Multiple Wireguard VPN config files imported through Keenetic WEB interface. Each config has different ports but with same IP and subnet.
On Android Mobile APP and through web interface each VPN config can be enabled and Keenetic router switches to that Connection if the VPN Config is enabled with "Use for accessing the Internet" along with "Connection priorities"
On the other hand on IOS APP this can not be done. Each config has a warning line "ip address conflicts with another subnet"
As described above this setup works perfectly if Android App or Web Interface is used.
