Yes, but by unlocking you lose every bit of physical security that device had. Anybody having physical access to your phone can then dump the phone's content to a usb drive in kinutes and without any other tool than a otg cable. The makers of the alternative recovery don't bother (who can blame them, they are volunteers) and the manufacurers don't care to implement a proper bootloader that would support reliable re-locking after installing a modified recovery. Besides that, all this alternative software is distributed binary on shady sharehosters by more or less random people on forums. Not exactly a good basis if you wanted to re-gain trust in your phone.
