FYI: you can adjust udevil mount options in latest LE11 and LE12 images by copying /etc/udevil/udevil.conf to /storage/.config/udevil.conf and then editing the file. After that reboot so the changes take effect.
Note that you'll also have to adjust allowed_options_exfat in addition to default_options_exfat
