The panel you linked to is an Evohome product, you don’t need the Envisalink for it. As far as I understood it has integration into HA https://www.home-assistant.io/components/totalconnect/
An alarm panel with out of the box home automation integration are rare … The only one I can think of is Satel through ETHM-1 plus or with KNX. All others as far as I know require some form of a hack job or third party integration.
With a little time and effort anything can be done, here is a Honeywell Galaxy panel integrated over MQTT with all options available. ( Also with the help of an ESP32, RS485 and RS232 module to get the data ).
Perhaps you can define what it is that you wish to control, keypad, zone status, output toggle, group setting etc …
