Numlock on login

Several of our work computers have the same issue of having the numlock off at the login screen when booting or restarting. All computers have BIOS numlock enabled. So when the computer starts or restarts, the numlock is on, but just doesn't remain. I've also disabled hibernate on all of them.

This issue is present regardless of the Windows version, which is either 1903 or 1909, and the few who have been updated to 2004. Noticeably, the issue seems to be much more prominent on computers with fresh installs since 1903, whereas those that had earlier 1809 and before who have since been updated just don't have this problem nearly as much (maybe a couple of them do). All are Windows pro (I think 1 is on Pro Workstation).

All Windows Hello functions are disabled domain wide by GPO.

Now I've searched a bit and saw that there may be something to do with the regedit but considering that I would have to manually go on every single one as admin, it's just kind of impractical. I need a solution that would preferably work as a non-admin user.

Any ideas?

The solution in the link does seem to work, although I did it locally on my own workstation. I'll see about doing it remotely on the others.
