Is there any way to run APK file on any IPhone without registering any devices

Hi team, We are new to Bitrise and have an react native app, and we already setup the Bitrise pipeline for both Android and iOS, this question is mostly related to iOS side.

Issue:
For code signing, we tried both Development distribution and Ad Hoc distribution, they all require us to register the device first (no matter on Bitrise, or on Apple developer portal), so that provisioning file can include that device and we can run the app on that device.

Goal:
We want to build the APK file and simply can run that file on any iphone without do any registration. Not on bitrise, not on Apple developer portal. Is that possible? And how to do that?

THANK YOU!

BTW, most docs about TestFlight are 404 now, is testFlight still available on Bitrise? Thank you
