[RPi] Can I disable the boot splash screen in order to see dmesg?

i don't make it to kodi (and have broken my network config apparently), can i modify something in the SD card filesystem to disable the libreelec splash screen in order to see the kernel logs?
also vaguely related question, is there a description of how the filesystem in libreelec works? i know there's the SYSTEM squashfs, but i assume there's also some overlay? where does that live? i found the .cache folder in the second partition (i'm on a rpi), but it doesn't seem to be a complete diff of what i've changed.

thank you

ah, i found .config - which is where the configuration i had broken was, so i am back in! but i would still be interested in disabling the boot splash.

i found this, but maybe it's outdated, because i couldn't find those files in the fat partition at all

super! thank you worked great
