Microsoft updated documentation [1] and clarified that ASLR cannot be disabled for Arm64 targets.

Because ASLR can't be disabled on ARM, ARM64, or ARM64EC architectures, /DYNAMICBASE:NO isn't supported for these targets.

Thanks

Okay, that's interesting.  In light of things like 7f3e17b, that may
be annoying.  Perhaps newer Windows versions are able to handle that
better.  I am wondering if it would be worth re-evaluating this
change, and attempt to re-enable that in environments other than
arm64.  This could become interesting if we consider that there have
been talks to cut the support for a bunch of Windows versions to focus
on the newer ones only.

Thanks for doing that!  Your post is just a couple of days old, let's
see if we get a reply on that.
