Question about Hyper HyperDrive Dual

I don't have an M1 Macbook but one from 2019, so this doesn't work at all? I would also like to connect two Dell screens in series, but unfortunately this is not possible as the screens are only cloned and I urgently need a solution. Connecting both screens to the laptop cannot be the solution. I have already bought 3 different docking stations and I am still stuck... Before I buy one I would like to know if it really works.
