That light setup looks great, well done!
As Ebiker01 said, your drive unit is 4th generation (any Class 3 or 28mph max. assist DU with a full-size chainring is 4th gen.) For reference, some 2020, and maybe even some 2021 products will still utilize 2nd generation drive units, depending on OEM design. In other words, model year is not always a positive indicator of DU design.
All of our 4th generation drive units use (6) "Torx-40 Plus" fasteners. Torx Plus, or Torx+, is more of a specialty interface, and a bit more common in automotive. We used it as it allows more contact area for a given cross section size, which translates to the ability to achieve proper torque specs with a shallower bolt head. We did it for clearance. During re-installation, your bike shop should be sure to use a proper alternating sequence for tightening, and carefully torque to 20 Nm. It is also critical to note that the mounting plates attached with Security Torx, or tamper-resistant Torx, should not be removed under and circumstance.
