Well, seems more is missing for aarch64 if devd hyperv is to be enabled:

# grep -r MK_HYPERV /usr/main-src/ | more
/usr/main-src/sbin/devd/Makefile:.if ${MK_HYPERV} != "no"
/usr/main-src/libexec/Makefile.i386:.if ${MK_HYPERV} != "no"
/usr/main-src/libexec/Makefile.amd64:.if ${MK_HYPERV} != "no"
/usr/main-src/usr.sbin/Makefile.amd64:.if ${MK_HYPERV} != "no"
/usr/main-src/usr.sbin/Makefile.i386:.if ${MK_HYPERV} != "no"
/usr/main-src/lib/libc/x86/sys/Makefile.inc:.if ${MACHINE_CPUARCH} == "amd64" && ${MK_HYPERV} != "no"
/usr/main-src/tools/build/mk/OptionalObsoleteFiles.inc:.if ${MK_HYPERV} == no

(The below is based on cgit.freebsd.org <http://cgit.freebsd.org/> in case my source tree
vintage is problematical.)

There is no libexec/Makefile.aarch64 or libexec/Makefile.arm64 .

For reference, libexec/Makefile.amd64 example:

# $FreeBSD$

.if ${MK_HYPERV} != "no"
SUBDIR+= hyperv
.endif


There is a usr.sbin/Makefile.aarch64 but it makes no
mention of hyperv:

# $FreeBSD$

.if ${MK_ACPI} != "no"
SUBDIR+= acpi
.endif
SUBDIR+= ofwdump


By contrast usr.sbin/Makefile.amd64 (for example) contains:

. . .
.if ${MK_HYPERV} != "no"
SUBDIR+= hyperv
.endif
. . .

I do not find an aarch64 equivalent of
lib/libc/x86/sys/Makefile.inc 's:

. . .
.if ${MACHINE_CPUARCH} == "amd64" && ${MK_HYPERV} != "no"
CFLAGS+= -DWANT_HYPERV
.endif
. . .
