Seems like I have a reversed case.
Is there any option / workaround to disable cross-partition moving for all trash operations?

Files deleted by Dolphin are moved from tmpfs to LUKS partition on SSD:

    $ pwd
    /tmp

    $ mount | grep /tmp
    tmpfs on /tmp type tmpfs (rw,nosuid,nodev,seclabel,size=32563000k,nr_inodes=1048576,inode64)

    $ ls ~/.local/share/Trash/files/testdel
    ls: cannot access '/home/andrew/.local/share/Trash/files/testdel': No such file or directory

    $ touch testdel

    $ dolphin # delete `testdel` file to trash in Dolphin

    $ ls ~/.local/share/Trash/files/testdel
    /home/andrew/.local/share/Trash/files/testdel
