There seems to be a trend for the system to be too "Smart" to make decision for us. But it boils down to UX designer really haven't considered a sizable minority has the SSD + HDD option where they didn't have a very big SSD because of the time they bought the PC/Laptop. There are workarounds that you have to go into safemode as those background processes are unloaded, move the folder to d driver and create a symbolic link, you almost have to do it for every software like this (there are ones that automatically install to appdata too). I have also tried to move the whole [program files] to another drive (you need to change NTFS ownership of windows store folder to successfully move it), but it will break Microsoft store apps (even calc), and after moving it will show "this system is not configured to use the software"(not the exact word, but something like that), but works for other software like Adobe CC suite, autodesk fusion360 (so that you don't have to reboot, move symbolic link every time you install a software).
