Yes it will. There's no way to bypass it, if there is, that would be a serious security flaw - the kind that would get patched very quickly. There have been some phones which had a vulnerable bootloader that allowed this in the past (eg: OnePlus devices), but there's no such exploit available for current generation devices
I'd like to see some sources backing up your claim, which is applicable to current generation phones.
And rooting the phone requires an unlocked bootloader, which would present a warning when the phone is booted up.
If you know what you are doing, it won't.
