Epic games seems to lack even basic functionality. I just added Win11 as triple boot on one computer, the kids have loads of games already installed from win10 in a tertiary drive ... on the website it says the solution to them not having a facility to tell their installer/launcher which folder to use is to reinstall all the games. Now, once you open Epic you can ignore it, use Explorer open the game folders and launch the games and they run. So it looks like they literally need a way to change a config file to avoid re-downloading 100s of GB of games. I find it literally crazy. They even scatter .egstore files around so actually scanning for and adding games to the library automatically should be easy. Steam makes the same task easy, and why wouldn't it it's pretty rudimentary for an installer/launcher to have a easy way for you to tell it where your downloaded games are. Oh, and the instructions for reinstalling Epic _launcher_ say to just re- download all your games. They're insane. YMMV.
