can i change bios settings without shutting down

[barrack_131]

after 3 days of trying to get the hp envy 23 AIO to boot again due to some error with the bios that could stem from the boot order, i set the boot order to cd>hard disk and it didnt start for 3 days (removed cmos battery and its still removed) if i shut it down it wont boot for another 3 days so is there a way to reset the bios without shutting down (cmos jumper and battery methods didnt work)

When clearing the CMOS, is the power cord unplugged (or PSU turned off)?
