I think it would be preferable to add to your /etc/apt/sources.list

  deb-src https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/

to get access to the source packages for R 4.0.2, and then do

  sudo apt update
  sudo apt build-dep r-base

and

  sudo apt source -b r-base

to build these on your arm cluster for your architecture. Of course you will 
need to rebuild after R releases to keep up to date.
