How do I remove Western Digital Unlocker as I no longer have the drive that installed it

This appears every time I boot my Mac Mini (Late 2014). It seems to be a virtual drive which can be un mounted but reappears on the next boot up. I seem to remember that this came with my WD Passport. I have no longer got the WD Passport and so can't access the soft ware that came with it. This has only been a problem since I updated the OS to Monterey (12.7.4). I do have four other WD MY Book drives and do not wish to affect or upset them. Can anyone help?
