TSM: 7.1.10

I'm trying to delete legacy mssql backup:

I never used any DSMAGENT parameters cause I use legacy mode.
How do I delete certain backup ?

Thanks,

I just noticed that delete command is for VSS only:

Use the delete backup command to delete a VSS backup of an SQL Server
database.

I needed to delete few small backups in order to move them to other management class.
If someone knows a way to delete legacy backup other than policy please share.
