Disable kernel lockdown on 18.04

I am trying to access a device connected through USB3 (an intel realsense depth camera), however I believe the kernel lockdown is blocking access to it.

dkms status

reads the proper camera, but when I try to check if data is being streamed with

dmesg -wT

I get a long output which culminates in this error message:

 Lockdown: systemd-udevd: unsigned module loading is restricted; see man kernel_lockdown.7

How can I disable the kernel lockdown so that I can gain access to this device?

I have tried this as suggested by a few posts, but it has no effect:

echo 1 > /proc/sys/kernel/sysrq
echo x > /proc/sysrq-trigger

If you want to use 3rd party unsigned kernel modules, you need to disable Secure Boot in BIOS settings.
