Latest Razor BIOS update has bricked my Razer Blade 14. Solutions?

I updated the BIOS on my laptop this morning and it completely bricked it.
Razer have pushed out a broken BIOS. It doesn't have a valid security key so won't boot without turning off 'secure boot'. But the BIOS has also broken the ability to turn off 'secure boot'. Creating an endless loop between the BIOS screen and the Secure boot screen.
I have a recovery image that I am going to attempt to install via USB but I don't think this will roll back the BIOS version which is the issue.
I need immediate help as I use this laptop for work.
