It could, but it would involve making a change in syzbot.
Specifically, syzbot would have to be changed to boot the kernel being
tested without the kernel.panic_on_warn=1 boot command line function,
and then in the syzbot reproducer, to add the moral equivalent of

echo 1 > /proc/sys/kernel/panic_on_warn

There appears to be a fix which has been reviewed; I found it by
searching lore.kernel.org for the string "drm: ensure blend mode":
