I have a new laptop: Acer Aspire 3, model A315-51-318M.
I can enter BIOS by pressing F2 at laptop startup.
On the Boot tab there is the Secure Boot enabled and I need to disable it.
The problem is the item is grayed out and also on Security tab there are most of the items grayed out by the way.
What needs to be done for me to change these item values?
