Restore on AC/Power Loss

Hey,
I have a question about BIOS function "Restore on AC/Power Loss".
In brief, this function start pc automatically after Power Loss.
I want to turn it off, but how can I do this without entering to BIOS ?
Is it possible to manage this function from desktop in settings or somewhere ?

Thanks in advance.

ok, thanks I will try it :)
