Jetpack 5.0.2 ACPI support

Hello.

Since the Jetpack 5.0.2 a ACPI mode for Jetson Xavier appeared as option

I tried to flash the Sample Rootfs then turn ACPI and PCIe options, but this cause device to hand during boot (see log below):

L4TLauncher: Attempting GRUB Boot

I/TC: Secondary CPU 4 initializing

I/TC: Secondary CPU 5 initializing

How can I enable the ACPI mode properly?

Is there any documentation regarding the ACPI mode in Jetpack 5.0.2?

Thank you in advance.
