So the issue with the Blue/Yellow appears to be when the serial driver loads, it for some reason resets GPIO 7 & 8. So the setting that the vendor put in /boot/config.txt gets overridden.

So, I put the following mini startup script in to run on boot. Script location-name: /etc/systemd/system/fixgpio.service Script contents below:

[Unit] Description=fix gpio for screen

[Service] Type=simple ExecStart=/usr/bin/raspi-gpio set 7-8 a2

[Install] WantedBy=multi-user.target

Then run service fixgpio enable and reboot.
