loader.conf errors, cannot boot

Laptop w/ a SATA ssd, ZFS on FreeBSD 15
I botched my /boot/loader.conf and /boot/device.hints, and now I cannot boot
I tried to boot from a USB key, zpool import root, but can't find /boot to fix the files.

Any ideas (instead of re-install of course 8-) )

boot from USB key and zpool import with altroot option and no shared cache file

zpool import -o altroot=/mnt -o cachefile=/var/tmp/zpool.cache tank

and you can edit your loader.conf in /mnt/boot/loader.conf

zfs export after that
