$ find /lib/modules/5.6.0-2-amd64/kernel/drivers -name '*storage*'
/lib/modules/5.6.0-2-amd64/kernel/drivers/usb/storage
/lib/modules/5.6.0-2-amd64/kernel/drivers/usb/storage/usb-storage.ko
/lib/modules/5.6.0-2-amd64/kernel/drivers/usb/gadget/function/usb_f_mass_storage.ko

Or the module is built in the kernel.
What tells "modinfo g_mass_storage"? If it's the same module as
usb_storage having the same parameters, then:

echo "options g_mass_storage delay_use=5" > \
/etc/modprobe.d/g_mass_storage.conf

It's a pretty old kernel, if it doesn't work and the module is built
in, one thing you might try is to put:

#!/bin/dash
echo 5 > /sys/module/usb_storage/parameters/delay_use

in a script /etc/rcS.d/00test.sh
