I don’t understand how it would work, as there is no image built for the VIMs,
RPI4 image is for the RPi4 only
also fastboot is not the only flashing method, you can use amlogic’s burning tool, available from here:
if you are interested in the linux version of kali linux, you are most welcome to flash a suitable linux image on an SD card and use my kali install script to convert the image to a kali image
best of luck!
