The most frustrating thing about these problems I'm having is they ultimately come down to "Android lets userland have *some* freedom, but you're not allowed to replace the nav bar". & it's infuriating because *Android used to allow this*. There used to be an entire ecosystem of "hide nav bar then add a custom nav bar replacement/gesture system". Around Android 10 Google summarily blocked this. And now I'm maybe gonna return a perfectly good tablet just because Lenovo botched their navbar tweaks
