Delete all backups of a file on an HFS+-formatted TimeMachine volume using newer versions of macOS without TMSafetyNet.kext

I'm trying to delete all backups of specific items backed up with TimeMachine on a backup drive formatted as HFS+ but using a Mac running Ventura. For a long time this was possible using the method described [here](https://apple.stackexchange.com/questions/333767/delete-all-backups-of-specific-file-folder-with-tmutil) and [here](https://apple.stackexchange.com/questions/180214/is-it-possible-to-use-tmutil-delete-or-another-command-to-delete-one-file-from) : The gist of it is don't bother with tmutil, use rm with the bypass helper script from TMSafetyNet.kext. I've used it successfully many times. Unfortunately, with newer versions of macOS TMSafetyNet.kext is gone -- not sure when exactly it disappeared, but it's no longer there as discussed [here](https://apple.stackexchange.com/questions/459407/macbook-pro-m2-missing-tmsafetynet-kext) (in a different context). Now, I've tried the following: First, using what seems to be the official method as described in man tmutil I have tried: sudo tmutil delete -d /Volumes/ -p /Volumes//Backups.backupdb///Macintosh\ HD/path/to/file/ I get: Invalid deletion target (error 22), Total deleted: Zero KB Now, the same backup from which I want to delete a specific file also has a backup of my system files, including TMSafetyNet.kext. I thought let's try the old method, pointing it to the backup of the bypass helper script: sudo /Volumes//Backups.backupdb///Macintosh\ HD/System/Library/Extensions/TMSafetyNet.kext/Contents/Helpers/bypass rm -rfv /Volumes/ -p /Volumes//Backups.backupdb///Macintosh\ HD/path/to/file/ It fails, because, as @nohillside points out in the comment below, TMSafetyNet.kext is not loaded. How can I delete all backups of a file on an HFS+-formatted TM volume on newer machines running a macOS version that no longer has TMSafetyNet.kext?
