• You can just get the posidriv bit for it.

    I don’t like the shorty torx bit that came with it so I took a regular bit and ground down the end with a bench grinder to make it a shorty bit. Worked well enough

    Edit: it doesn’t appear that there is a posidriv shorty bit for it on lttsrore.com. But I believe wera sells 20mm bits and I’m certain they have a posi one

    Edit2: after some looking I found this:

    NordWolf 20-Piece Low Profile Offset 15° Angle Mini Reversible Ratchet Wrench and Screwdriver Bits Set, Includes 19mm Square Head/Phillips/Pozidrive/Torx Security/Hex/Slotted Bits in Storage Box

    Seems to be exactly what you needed.
