Note: This question is different than: Can't edit read only file even when root

I am trying to edit /System/Library/QuickLook/Illustrator.qlgenerator/Contents/Info.plist.

On MacOS Ventura (Mac M1). I have already disabled System Integrity Protection.

❯ pwd
/System/Library/QuickLook/Illustrator.qlgenerator/Contents
❯ csrutil status
System Integrity Protection status: disabled.
❯ sudo chmod 777 Info.plist
Password:
chmod: Unable to change file mode on Info.plist: Read-only file system

What am I doing wrong here? asciinema video

As @Tetsujin commented: Since BigSur, the System Partition is sealed as read-only and one cannot change this even with root and disabled System Integrity Protection.
