'/dev/block/dm-0' is read-only

I want cp certificate in /cacert, However, an error occurs during command execution；
The command is
mount -o rw,remount /
mount -o rw,remount /system
mount -o rw,remount /dev/block/dm-0 /system

Google search is the solution：adb disable-verity

However, after I execute the command, a new error is still generated：
