It won't work. You have to restore backup of partitions altered by this kernel.
You can also try other methods mentioned in comments above.
this is for anyone that was asking about the easiest way to do this process:
(if you don't have dtbo/vendor_boot/boot img's backed up): go to the telegram group for this kernel, find the user 'ileux' who posted 11.2.9.9AA img's, download all three (he posted an already magisk patched boot img), reboot to fastboot, run:
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vendor_boot vendor_boot.img
reboot to oos
then local upgrade 11.2.10.10 (don't reboot when done)
flash twrp.zip from nebrassy's thread in magisk (if you use twrp) - don't reboot
flash magisk to inactive slot
- now reboot
