Hi,

As per my knowledge, there is no such option but you can make Signature based SSL Site to Site VPN between two FortiGate devices.

But same time, I don't think, your ISP has blocked these ports becuase its required for business or home VPN as well. I advise for reconfirming from the ISP.  If you are behind the NAT then, please check IPsec bypass, UDP port 500 & UDP 4500  are configured properly.
