Managing the Menu Bar Icons

Is there a way, (without using any menu bar apps like Bartender) to manage the icons in the menu bar?

Currently on my M1 MacBook, I have filled up the right side menu bar with app icons until the center notch. Is there a way to get more icons to show on left side of notch also?

Also I think some icons are hiding behind notch - can I get to them?

I thought there was a way to make apps - “Scale to fit below built-in camera” but how do I do this with the finder?

ok thanks for the help
