There are a few things you can try -- hopefully one of these helps. It's definitely less intuitive than is ideal.
If you're on any of the Home Screens (icons), you can swipe down in the middle of the screen to pull up Search, which you can use to more quickly get to settings rather than trying to scroll though apps to find it. Alternatively, you can put the Settings icon in the "app tray" that's on every Home Screen, rather than whatever the defaults are.
Settings also has a semi-hidden search mode, which you can get to if you swipe down in Settings (scroll all the way to the top).
Finally, "Control Center" has a Hearing control you can add -- I'm not sure if this integrates with the hearing aids, but it might let you have a much faster way to get to the specific settings if that's compatible.
