Why each option
BIOS intrusion detection is a security feature that monitors whether the computer chassis cover has been physically opened and alerts the user on next boot.
Boot sequence settings control the order in which devices are checked for a bootable OS and have no relationship to physical case access.
Date and time clock settings configure the system RTC and do not interact with physical sensors on the chassis.
Intrusion detection in BIOS/UEFI uses a physical chassis intrusion sensor (a small contact switch on the case) that registers when the cover is removed. When enabled, the BIOS stores this event and displays a chassis intrusion alert on the next POST. This feature is designed to detect unauthorized physical access to the system.
Virtualization support enables hardware-assisted virtualization (Intel VT-x or AMD-V) for running virtual machines and is unrelated to chassis intrusion.
