S24 Ultra: Can't change resolution

[Ceejus]

Trying to get an 800x480 resolution from my S24 Ultra to my 2016 Honda CR-Z radio via USB-C to HDMI so I can use navi without having to replace the radio. I have USB debugging enabled on the S24 and I used adb shell pm grant com.farmerbb.secondscreen.free android.permission.WRITE_SECURE_SETTINGS from a Windows 10 machine. However, everytime I go to adjust the resolution within SecondScreen, I get a pop-up telling me that in order to protect my screen, it won't allow me.

I did manage to lock the screen in landscape when connected over HDMI but couldn't do anything with the resolution.
