How to update dtb in 36.3.0?

hello, I used the method of overwriting dtb under /boot/dtb, but did not execute the new dtb. I can do it in 35.5.0, may I ask what configuration needs to be done in 36.3.0 to achieve it

The FDT entry in /boot/extlinux/extlinux.conf is removed in JetPack 6.
You either add this line back or re-flash the A_kernel-dtb/B_kernel-dtb partition.

YES. Exactly.
If this line is not specified, bootloader will load kernel dtb from the dedicated partition; if it is specified, then the file in rootfs will be loaded.

Thank you,DaveYYY
