Unable to uninstall/update manually installed Nvidia driver

[midget214]

I am having some trouble uninstalling an older Nvidia driver on Proxmox (v7.1-12). I previously installed driver v470 using a run file from Nvidia's website and its been working fine. I do however want to update the driver as this one is very old.

I first tried to uninstall the driver using the run file (had to redownload that specific version as I deleted the old one) using ./NVIDIA-Linux-x86_64-470.103.01.run -uninstall but the installer shows the following :

There is no NVIDIA driver currently installed.

I then downloaded the latest driver (v535) which shows

The NVIDIA driver appears to have been installed previously using a different installer. To prevent potential conflicts, it is recommended either to update   
  the existing installation using the same mechanism by which it was originally installed, or to uninstall the existing installation before installing this     
  driver.

  Please review the message provided by the maintainer of this alternate installation method and decide how to proceed:

and if I select continue installation it shows

If you want to use the nvidia-installer please uninstall the Debian packages
first.  The two methods of installation cannot be used at the same time.

Running nvidia-smi shows the following

I'm not sure what else I can try to update the driver.
Edit: I should add that as far as I can remember I haven't installed any debian packages for Nvidia.

This is not a PVE matter, but a nvidia one. Have you asked in their forum because it's their software?

Generally: Installing stuff in Linux not via package manager will clutter your machine (as it does on windows).
