What is the source of this tty console output?

I'm making a kiosk system using Armbian on an orangepi zero 3. The kiosk is a on a local server that I connect to using chromium browser launched from my ~/.bash_profile. Before chromium-browser starts up getty@tty1.service is launched and autologs in my user. When the getty terminal launches there's a line that prints and I can't seem to find the source. The line printed is Armbian 23.08.0-trunk Jammy tty1 I've tried changing sysctl kernel.printk to all zeros and dmesg -n 1 but neither of these work.
