I'm trying to break this down further:
This block is the set of keys which I've included the byte output for in
a reply further back, repeated for clarity. This block is currently not
interpreted by the kernel as anything I guess due to the vendor specific
page:
0x06, 0x31, 0xFF, // Usage Page
The USB descriptor for the affected device:
0x06, 0x31, 0xFF, // Usage Page (Vendor Defined 0xFF31)
0x09, 0x76,// Usage (0x76)
0xA1, 0x01,// Collection (Application)
0x85, 0x5A,// Report ID (90)
0x19, 0x00,// Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage
The key thing I've noticed here is that if I grab the device via libusb
and capture data, then it's on interface 0x83, and the bytes are a
little different to the keys that do work (like vol+).
For example Vol-Down gives:
[2, 234, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
Apologies, the last attachment is Linux capture data (as per filename)

It is a fresh install never tried an older version.
I have tried the new kernel, same issue.
The asus-nb-wmi module is loaded but seems not to support this keyboard.

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.20
Fedora 29, same thing. Doesn't start in graphic mode. The only version that
seems to work is Linux Mint 19 at the moment.
I've added an output of inxi:

Ubuntu 18.10 does not work on this laptop, at least not the live version. It
blocks on the GPU.
In linux mint it works smooth, apart from the keyboard backlight.
