How to replace battery for SNVS without clean ZMK?

[brucezhao]

Hi,

    I am working on IMX8MP evk，I want to implement tamper protection, When tamper happened, ZMK will be cleaned. In my opinion SNVS works in power-always-on domain, so we need to place a cell battery.

    My question is when cell battery is dead，the ZMK will be cleaned? And do I have any way to replace a new battery without cleaning the ZMK?

    Thanks.
