This message comes from NVIDIA, not from any Amber code. You can either
install gcc8 and use that, or move to CUDA 11. See:
https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html
Note: please don't try gcc10 (yet): there are a few pieces of AmberTools
that don't work with gcc10.
Second note: upgrading to CUDA 11 won't help if you need amber18 GPU
code; you'll have to downgrade gcc. Amber20 is fine with CUDA 11.

You don't need to install gcc8 on the system, or even have root
privileges: just put gcc8 somewhere (say in a folder under your home
directory). Then create a ~/gcc8bin folder that links gfortran, gcc and
g++ to the gcc8 binaries. Finally, put ~/gcc8bin at the start of your
PATH. Your amber build will then use gcc8. Remove ~/gcc8bin from your
PATH once you are done, and you'll be back to gcc9.
