Sorry I don’t have access to a Shift device, but typically if you make sure that “Allow OEM Unlocking” is enabled before you install, then if you do hit ARB or another issue and it won’t boot, you can always unlock and retry again. This “belt and suspenders” approach for extra safety gets you to a running system, if all is good and you want to disable “Allow OEM Unlocking” later that is easy to do.
Sorry I don’t know an answer to this, more knowledgeable people will have to help answer
