DEFAULT_BOOT_DEVICE has been blocked by current security policy

Greetings,

I'm new to Linux and I wanted to try Artix Linux. Although I've come across secure boot violations. Any help or advice is appreciated!

Issue:
From what I've searched for it seems Artix Linux does not come pre-signed similar to Arch Linux, and unlike Tails (Debian based) and Linux Mint (Ubuntu based) which are pre-signed.

Questions:

How hard it is to sign it myself? And will it need re-signing after updates?
In terms of security, is it incorrect to make an exception to secure boot security within BIOS?

Notes:
I'm using a Dell G15 5535 running the latest BIOS version 1.12 provided by manufacturer.
I'm trying to install Artix Linux through a USB flash drive.
