Protect UICR registers using ACL

[Thomas]

Is it possible to configure the ACL to protect the UICR registers?

If so, would this have any impact on the SoftDevice or other nRF52840 peripherals? I.E does the SoftDevice require access to these registers during runtime or is it possible configure the ACL after enabling the SoftDevice

No.. one even could not write an address 0x10001000 to ACL register. Perhaps you can do this with MPU module.
