Cannot edit ntfs-3g

[knightjp]

I am trying to edit the NTFS-3g after installing it. Following the instructions from the site below.

​https://trac.macports.org/wiki/howto/Ntfs3gFinder

But even though I try the following like I did for Catalina, "sudo mount -uw /"

But I get this error...

mount_apfs: volume could not be mounted: Permission denied
mount: / failed with 66

I tried disabling SIP, but that does not work either. After disabling SIP, when I do this command,

sudo mv /sbin/mount_ntfs /sbin/mount_ntfs.orig

I get this error,

mv: rename /sbin/mount_ntfs to /sbin/mount_ntfs.orig: Read-only file system
