verify signature during fastboot flash

Hi NXP

I'm working with a board powered by imx8 processor(nitrogen8mm) with android running in it. I couldn't find a way to sign and verify the keys present in all the images(boot.img, vendor.img, recovery.img, system.img) to be flashed. I need to verify the signature while flashing using fastboot. is there a way to do that?. If there is a way can I know how?

Thanks for the reply,

But this document is all about signature verification during boot.

I need to verify it during fastboot flash. Can you please tell me if there is a way?
