How to get from Windhoek to Palmwag

At the end of April 2020 I’ve booked an 8-day tour from Khowarib Lodge, just north of Palmwag, into Kaokoland. I need to get from Windhoek to Palmwag. I could hire an SUV which I think is OK for the roads to Palmwag. But then I need to leave that car for 8 days during the safari (there’s no way I would take a hire car to Van Zyl’s Pass). Anyone have any suggestions?
