Probably a good idea to reset bios to defaults, and then reapply setting you had before one by one.

1. Control Panel > Power Options > Choose what power button do : Enable Fast startup

2. Are you calculating boot time including POST time (Where it stays at Dell logo) I have seen Del BIOS update messing up with Boot Paths and Boot RESET BIOS to default

I know the last one will sound illogical But update windows, it does help

Unfortunately, bios reset won't work as the newer version is burned.. Take your laptop to the dell technical expert so they can replace bios using bios programmer device..
