Will I ever be able to install unity onto my secondary hard drive?,Will I ever be able to install unity on my secondary hard drive?

My main hard drive has nothing left that I can uninstall to free up space so it only has 1.4 GB of storage remaining and recently I bought an External Hard Drive with 500GB of storage. So I install unity hub, but when I try to install unity version 2020.3 it still doesn't work (I also tried newer versions). I also tried installing it from the download archives and it still didn't work. Please help:(
