There’s no such thing as hass.io docker, that’s not only unsupported, that’s not even an install method. The different install methods can be found here.
Also the term Hass.io has been deprecated for around 6 months now. What you are using now is Home Assistant Supervised and it’s not meant that you run your own docker stack, by doing this you are asking for trouble and make your life harder than it needs to be. If you want to configure your own docker containers use HA Core.
What’s the goal of all this? What different configs are you testing?
For me it feels like you are overcomplicating things.
