iOS new tab page: disable background images

I recently installed Brave on my wifey’s older iPad. Now as far as I can tell she’s content with it. When I used the tablet today, I found that the new tab page displays background images, though. And even sponsored ones it seems.
It’s just that my wife and also other relatives whom I recommend Brave to are miles away from technical stuff or even Bitcoin!
To them it must seem cheesy just like any of the shady websites Brave handles so well.

I’d really like an option to disable images at all on iOS’ new tab page. On top of that comes that it’s a old tablet and every superfluous action should be skipped, so

Please make it that background images can be turned off!
