I use ios 14.4.1 and same or similar ipad and i can say : there is no official way for force zooming. Things you can use to have similar effect :
- Fullscreen zoom in accessibility settings you can modify zoom and for example - make it fullscreen or control with keyboard - but there is only one thing - you need to remember to double tap screen with 3 fingers and move zoom with also 3 fingers ( because „normal” scroll acts normally as without zoom ). I don’t share screenshot here because zoom resizes that to size same as without it...
- resize font (only in accessibility settings and in shortcuts) to make font size up to about 1000 times bigger than normal and it resizes also icons, ( i just saw that when moving this font-slider in setting and watching icons of settings’s tabs ) it’s named „enable bigger fonts” and should be over this place where you choose font size - [/settings/accessibility/screen and text size/text size/larger fonts] here is maximum size of text (and even other things) by enabling that ( i also use ipad) :
you can also bold text if you want in category above text size.
Btw - you can force that but then it’d really be hard and then you’ll need to modify ios.
