system launch debug mode removal

[threerocks863]

There's lots of debugging messages print out during boot session, I try to find -v in config.plist, but it's not there, but "keepsyms=1 -v" always appears on boot menu

The boot args may be saved in your nvram. Press F11 in the Clover interface to reset NVRAM would clean up these args.

Seems still not working, I looked into clover configurator nvram, the boot arg always has debugging info as above picture shown, but once I removed, it came back again...

Do you have any idea of this, thanks.

You could try nvram command.
Run sudo nvram -d boot-args can remove boot arguments.

FYI: Is there a list of available boot-args for darwin / OS X.

Thanks for your idea!
I ran the command sent to me, but seems not working, then I did some investigation online and turned off SIP and tried to set boot-arg empty(recovery mode), but system Catalina disallowed me to do this, I don't know if I need to set other parameter off before set boot-arg.
