While grepping through /usr/src I found the driver in
/usr/src/sys/contrib/dev/mediatek/mt76/mt7921/ and a make && make
install in
# cd /usr/src/sys/modules/mt76
# make
..
# make install
===> core (install)
install -T release -o root -g wheel -m 555 mt76_core.ko /boot/modules/
kldxref /boot/modules
===> mt7915 (install)
install -T release -o root -g wheel -m 555 if_mt7915.ko /boot/modules/
kldxref /boot/modules
===> mt7921 (install)
install -T release -o root -g wheel -m 555 if_mt7921.ko /boot/modules/
kldxref /boot/modules
installs it fine. There is also a manpage in /usr/src/share/man/man4/mt7921.4
(attached)
I still have to build the firmware from ports/net/wifi-firmware-mt76-kmod.

MT7921(4) FreeBSD Kernel Interfaces Manual MT7921(4)
NAME
mt7921 – MediaTek IEEE 802.11ax wireless network driver
SYNOPSIS
The driver will auto-load without any user interaction using devmatch(8)
if enabled in rc.conf(5).
Only if auto-loading is explicitly disabled, place the following lines in
rc.conf(5) to manually load the driver as a module at boot time:
kld_list="${kld_list} if_mt7921"
The driver should automatically load any firmware needed for the
particular chipset.
It is discouraged to load the driver from loader(8).
DESCRIPTION
The mt7921 driver is derived from MediaTek's Linux mt76 driver and
provides support for the following chipsets:
MediaTek MT7921E (PCIe)
This driver requires firmware to be loaded before it will work. The
package wifi-firmware-mt76-kmod from the
ports/net/wifi-firmware-mt76-kmod port needs to be installed before the
driver is loaded. Otherwise no wlan(4) interface can be created using
ifconfig(8).
The driver uses the linuxkpi_wlan and linuxkpi compat framework to bridge
between the Linux and native FreeBSD driver code as well as to the native
net80211(4) wireless stack.
While mt7921 supports all 802.11 a/b/g/n/ac and ax the compatibility code
currently only supports 802.11 a/b/g modes. Support for 802.11 n/ac is
to come.
BUGS
Certainly.
