Have a look at this WP: https://www.hpe.com/h20195/v2/GetPDF.aspx/4AA3-8987ENW.pdf

It doesn't tell you details on how to do it, but you can create a zerofile using dd and then remove that file to free up space. However, you shouldn't fill up the fs with the zerofile so you might have to script out something that would check the free space and create a zerofile that fills up maybe 80% of the fs then delete the zerofile. See here for discussion on using dd to create zerofile -> https://community.hpe.com/t5/System-Administration/using-dd-command-to-zero-out-disks/td-p/3211512

Just be careful when you issue dd and rm, you won't want to dd or rm and existing file in HP-UX....
