Hi, i didn't quite know where to post this, so apologies if i am posting in the wrong place.

I have an XE303C12 Samsung ARM Chromebook. I am using developer mode, and i do NOT want to turn developer mode off / OS verification on.
what i want is to change the 30 sec wait to something like 2 sec and stop it beeping when i turn it on, without having to press ctrl D.

thanks in advance,
