brew install ntfs-3g
volname=Toshiba_1tb diskutil list | grep $volname 1: Windows_NTFS Toshiba_1tb 1.0 TB disk2s1

sudo mkdir /Volumes/$volname
From https://github.com/osxfuse/osxfuse/wiki/NTFS-3G :
If volume is APFS, then it will need to be unlocked to install mount_ntfs. Let's assume that Macintosh HD is identified as disk1s1.
diskutil list diskutil apfs unlockVolume disk1s1
To replace Apple's NTFS mount tool with the one provided by NTFS-3G execute the following commands in Terminal. This will back up the original mount tool to /Volumes/Macintosh HD/sbin/mount_ntfs.orig.
sudo mv "/Volumes/Macintosh HD/sbin/mount_ntfs" "/Volumes/Macintosh HD/sbin/mount_ntfs.orig" sudo ln -s /usr/local/sbin/mount_ntfs "/Volumes/Macintosh HD/sbin/mount_ntfs"
or why not simply : (to try)
sudo mv "/sbin/mount_ntfs" "/sbin/mount_ntfs.orig" sudo ln -s /usr/local/sbin/mount_ntfs "/sbin/mount_ntfs"
Maybe simplify with unmount/mount? See https://apple.stackexchange.com/a/338692/14586
