Confirm the method to upgrade the NV driver for ubuntu 18.04

Hi

Would you give us the official way to upgrade the NV driver?
I installed the cuda 11.1(cuda-repo-ubuntu1804-11-1-local_11.1.1-455.32.00-1_amd64.deb) to our server and it installed the R455 driver which this package was included for this server. But I need to upgrade the nv driver for R465 to fit the software requirement with holding the cuda 11.1.

Best regards.
