It just died, Uptime 2d 14h 23m 22s. :-(

Shouldn't modinfo list the available parameters?
# modinfo mt76_usb
module:         /lib/modules/5.4.48/mt76-usb.ko
license:        Dual BSD/GPL
depends:        mt76,mac80211
name:           mt76_usb
vermagic:       5.4.48 SMP mod_unload aarch64

# ls /sys/module/mt76_usb/parameters/
disable_usb_sg


# cat /sys/module/mt76_usb/parameters/disable_usb_sg
N

I've tried a few things in /etc/module.d but nothing worked yet.
I unplugged the dongle and did:
# echo 1 > /sys/module/mt76_usb/parameters/disable_usb_sg
I plugged in the dongle:
# cat /sys/module/mt76_usb/parameters/disable_usb_sg
Y

I found this old post that helped:
