Is it possible to use Checkpoint SSL (SNX)

I have a customer that has CheckPoint SSL VPN, although I can use their program installer. What I want to do is to add the VPN to the router that as OpnSense, I have been unsuccessful to use configure it even with juniper protocol.

I was hoping for either some hints on how can I configure this, or my to my limited knowledge how to add this to the OpenConnect source.

Thank you
