Pi + Hass.io + Pi Display?

Hello. I don’t know if I’m posting this in the wrong section. Let me know if I did.
I am currently running the newest 0.78.1 version on a Pi with Hass.io installed. Now I have the official Pi display connected to it and I only get a console view obviously. My original plan was to create a wall mounted touch display with a Pi mounted to its back. Is there any way I could go about doing this with Hass.io or would I have to install Home Assistant manually on some Raspbian or other Linux distro?
Thanks for your help and input guys!

This is not possible with Hass.io

How would I go about implementing it? Can I use a Raspbian or Raspbian Light image and run Home-Assistant manally there and simultaneously use the whole thing as a wall-mounted panel?
