iPad “Not backed up” notifications on iPadOS - how to turn off

Hello,

My iPad keeps getting a very excruciatingly annoying not backed up notification coming up constantly on the screen. I do not have a normal Wi-Fi in my apartment due to financial issues I 100% have to rely upon my 4G LTE hotspot on my iPhone 8+ which means that I cannot do a back up while I am on my hotspot because the system is not designed to do it that way I must wait until I get to a normal public Wi-Fi at like a library or a coffee shop somewhere to do my back ups. I get this obnoxiously annoying message coming up constantly

I am a level one helpdesk for computer support with 25 years experience in the business for multiple corporations so I know my way around technology. I have searched the settings on both my iPhone and my iPad and I cannot find it anywhere at all to turn off this annoying message. As a tack the pit of my stomach is telling me Apple has been a bunch of idiots and not provided a way to turn off system notifications either completely or by notification based on what it is for. I am praying by coming to the community that I find out that I am wrong and that they do have a way to turn off this disgustingly annoying notification. Can anyone tell me one way or another as to if there is or is not a way to turn off this horribly annoying constant notification.

I appreciate anyone’s assistance with this I do not want to wind up in a mental hospital over this.

Sincerely,

Wonder Woman
