Essential ;) Papyrus and Party LET fonts, cannot even be deactivated in Font Book?

The font selection dropdown in Adobe apps is fine ... as is the Creative Cloud system app and web-app to activate more Adobe subscription fonts.

But on MacOS that dropdown is polluted with tonnes of junk essential system fonts, including all the foreign language ones MacOS won't let me disable. That makes the fonts dropdown in Adobe apps not much fun to browse fonts in, but so it is (unless I have missed a trick?)

But for some reason Apple thinks Papyrus and Party LET are essential too. These are locked from deletion and even locked from deactivation in Font Book.

Is there some way to rid my font selector dropdown of Papyrus or Party LET?

And futhermore is it safe to delete from /resources/required/fonts the junk fonts Adobe adds, like TrajanColor-Concept.otf ? These are hidden from the Creative Cloud system app font list just to make them harder to eliminate too.

Hoping for a dropdown list of only the fonts I've activated myself ... is that impossible?

Regards.
