只有 已越狱设备 可以

[Suclogger]

@chinvo 14.3 以下版本的，基本都可以越狱

@chinvo 而且不越狱也是可以的，参考： https://gist.github.com/dhinakg/035dc585a0de54b6a34cf72a2a36016e

If you're not jailbroken - wipe your phone and supervise it with Apple Configurator 2 (on macOS, free), or with iMazing (on Windows, might be paid).
Already have data already? No problem. Back up your phone, wipe and prepare, update, then restore backup.
DON'T BACKUP IF YOU'RE JAILBROKEN
Restoring a backup will unsupervise your phone (unless you made the backup while supervised), so make sure you update before you restore your backup.
This is personally what I used, as I had a new in box iPhone SE with 13.4 installed.
more on how to do this later
