Pixel 6Pro updated from A15 to A16: can I change the UI for answering calls back?

Every few updates, Google seems to hire a new team of UI engineers and it's annoying. I'm too old to change! grumble grumble etc.

On Android 15, I swiped up on the green phone soft button to answer calls. Now it's just a button. I swear at one point on previous versions it was a swipe-to-center.

Is there anyway to change the behavior back to swipe up? Is this a component that I can replace entirely to keep it stable?

I'm using Nova launcher (disallowed updates since they were bought by someone sketchy) and I am playing with F-Droid, if that helps.

TIA!
