Android admin/root privilege without voiding warranty?

is it possible to enable root without voiding warranty, at least for temporarily so power users can change hidden settings, access to root files for backup or customisation purposes etc and then disable root when needed? I think that would be great to have root/unroot option builtin on android like enabling/disabling developer options. Otherwise it takes extra time to root/unroot a device with 3rd party tools and has risks of bricking device, voiding warranty etc? Having root/unroot option would be really good for many power users and developers out there. Cheers
