Options for Lovelace on older iPad (ios 9.3.5)

i installed home assistant via this image:

as i understand, i don’t run Home Assistant in a docker, so i have no easy option to access the root OS (which is Hassio?)

do i have any option to install firefox as a docker so i can access it via an old ipad3?
maybe someone can help me because im a little bit lost here, and i don’t want to redo everything again to install first raspian or any other os and on top the home assistant.

thx and best regards @all
