Mac – remove old drive from Time Machine backup

hard drivetime-machine

My old HDD died, I restored data to a new one, but now I have two versions of backup: new and old
The name was MyVolume, in Time Machine I have now MyVolume and MyVolume1

I already tried tmutil addexclusion and exclusions in Time Machine options
I tried to rename my new HDD, tried to use another empty HDD with the same name
but this old backup is still there

How can I remove one of it?

I found a solution in this answer: How can I delete Time Machine files using the commandline

I used /System/Library/Extensions/TMSafetyNet.kext/Contents/Helpers/bypass and it worked for me
