which OS do you use? you're config options are legacy and will be ignored by the KMS driver (which IS Default in bookwork).
as you're screen in non working when running legacy graphics driver - which IS what you get when commenting dtoverlay=vc4-kms-v3d - sounds like there is a problem with these settings as well.
try using 'dtoverlay=vc4-kms-vga666' overlay under bookworm. requires dtoverlay=vc4-kms-v3d to be loaded.
If that's Not working ask your HAT manufacturer to support
