How do I increase the number of rings?

I've just received this new Pixel 8, unfortunately I'm over the return date as I don't like it at all!   Wished I'd stayed with Samsung!  Have been on the phone with my provider everyday to figure out a problem, turns out it was the phone, I told them it was but they didn't believe me!

Anyway, I often can't get to get the call to pick up in time so I want to increase the number of rings or length of time to pick up a call!

I can't find the answer anywhere, I'm hoping that someone can help me, thanks, Susan
