Remove the floating home button

You have likely enabled Assistive Touch --> Use AssistiveTouch on your iPhone, iPad, or iPod touch - Apple Support

Do you mean the blue/pink ring at the bottom right? If so that isn't a Home button but a button to access Meta AI. Doesn't seem to be a way to disable it.

You're welcome. AssistiveTouch on iPhone is an accessibility feature designed to help users perform actions without using physical buttons or complex gestures. Most people, especially those who don't have disabilities don't need to use this feature. I'm not sure it has anything to do with having a linear or calm environment?
