Recommended way to integrate iobroker into HAOS

I am planning for migration from iobroker to home assistent on my raspi 4.
However, I need to keep iobroker as it provides full integration for many of my devices connected to my Lupusec XT2+ alarm system, while the HA add-on does not yet support most of them. I learnt this should be simple via MQTT.

My question: How can I use all of HA and containerized add-ons on HAOS while running also iobroker in parallel in the same raspi 4? What is the recommended or best possible way? Should I get host system ssh access, and install iobroker in a container parallel to HA? Is there a better approach?

Thank you.
