I had the same problem on my PCSpecialist laptop and was able to free up around 20GB of space by removing these duplicate entries using DriverStore Explorer. I created a retore point first though, just in case
First, I sorted by driver version. Then I went to all the NVidia Display Adapter entries. Having updated my graphics drivers when I received my laptop, I saw there was one entry with the latest version and a whole load of entries with older versions. I ticked all the boxes for the older driver versions except the one with the highest filename number and the one with the lowest file name number (not sure which was best to keep, but I wanted one in case I needed it for rollback). Then I clicked delete and after a while I had 20GB more space on my drive
The NVidia graphics still seem to work fine, even after rebooting and everything.
