How to completely and permanently remove a system app from Android?

I'm using Android 14 with KernelSU root access and TWRP recovery on a OnePlus 12 running OxygenOS 14. **What I've Tried:** - I can see /product/app/YouTube/YouTube.apk using Termux or Root Explorer when the system is booted, but I can’t delete it because it's read-only and mounting doesn't seem to work. - TWRP doesn’t show the /product/app/YouTube folder, so I can't access it through recovery. - Tried uninstalling YouTube using Lucky Patcher, but it reappears after reboot. **Question:** How can I permanently delete the YouTube app and prevent it from returning after each reboot? I'm not looking to just disable it; I want to completely remove it from the system.
