Hi sjesse,
As far as I know, only admins can install fonts, so that will be tricky, I think.
I did (just now
find out that as of Windows 10 Version 1809 there's an option for non-admins to install fonts (just for their own use, i.e. the fonts won't be available system wide). That seems to result in changes in one folder and one registry key:
From a (very quick) experiment it seems to work if you just capture that folder and registry key with UEM.
