Does setting M1 Mac NVRAM "auto-boot" to false still cause boot issues?

I'd like to disable the auto startup feature, but from what I can tell, there are reports that changing this setting causes issues with booting, including not being able to boot at all. This is about NVRAM "auto-boot" not "AutoBoot".

I know auto boot is the intended feature, I've tried altering the AutoBoot variable, and I tried looking through existing issues to see if there was any up to date info.

Because I know someone will ask: if I wanted my computer to be ready to go when I open it, I would put it to sleep. Shutting it down should keep it shut down until I explicitly tell it to boot.

I know of no command line that turns this feature off on M1/M2 SoC Mac...

You can submit your Apple Feedback here: Product Feedback - Apple

if it is a feture you would like to have control.

I haven't seen anyone post anything about this "nvram" command since the M1's were released in 2020 where a couple users reported having major issues, even suggested their M1 Macs were bricked, by using those nvram commands. I won't even try it until I have an M1 Mac which is going to be be junked or will need a new Logic Board as it is not worth the risk to find out.

Like @leroydouglas mentions I am not aware of any option to disable auto-boot on an Apple Silicon Mac. In fact, this option on the Intel Macs only affects auto-boot while opening the Display and not the pressing of any key to power on the Mac.

I would be very cautious using options that are not verified to be compatible with the M1/M2 Macs. Of course it is your laptop. Remember a Logic Board is an expensive repair if the "nvram" command bricks your Logic Board. No idea whether a "Restore" will do anything to fix any problems the "nvram" command may cause.
