Opening excerpt (first ~120 words) tap to expand
It's part of Vanguard. As Vanguard hooks itself into the Windows kernel through a low level (ring 0) system driver and all partitions except the system / UEFI service partition are not available at boot/init time (which is the moment Vanguard is loaded and activated) it uses the UEFI service partition to dump files it temporarily or permanently requires.If you no longer play any of Riot's games (which you should if you really care about the integrity of your system) and Vanguard is no longer active on your system you should be able to safely remove it.
