G_mass_storage module file not found

HI,
New here and I would like to use my VIM2 as USB flash disk for my Tesla,
current EMMC image is ubuntu server with kernel 3.14.29.
I have tried
modprobe g_mass_storage but it said no module in the module folder. how I can solve this? do I need to rebuild the kernel or is there an image with those modules?

Thanks

Anyone please, am I able to use VIM2 as gadget flash disk (USB flash disk)?

Plz try Krescue

Its easiest way - automatically export all device storages as USB disks
