Can you hide fonts in Libre Writer selection bar

I am trying out Linux for the first time so don't bite my head off. I searched this topic and anyway blah blah blah.
In Writer, when I go to choose a font, there are hundreds that preview that are in all sorts of non-Latin alphabets.
I went through the terminal commands to purge the noto files but there are still, literally, hundreds I have to scroll through to get to the fonts I want.
So then I tried to install font manager, the terminal says unable to locate package font-manager.
So I search online it talks about marking stuff for installation, but I can't find anything on how to mark something for installation.
The app is essentially useless with all these fonts glomming it up. Is it even possible to fix this? And no, I don't have anyone to ask. No one I know uses Linux.

This is an issue that comes up on occasion and in my opinion, LibreOffice is to blame for not filtering fonts.

Many packages depend on certain fonts and you can end up with thousands - especially as many users are cross platform, even when Windows OS users stick only to Windows OS fonts; GnuLinux users use Windows, GnuLinux and Mac fonts.

Removing the Noto fonts is not viable, since many we be readded as dependencies later. Or applications that depend on them can break.

But there is an easy workaround.
Create a folder in your home directory named .fonts or you can create it in .local/share/fonts
To reveal the Hidden System Files in your home directory tap ctl+h and you will then see the .local folder. Tap ctl+h to rehide them if you want.

With your new fonts folder created, move into it only the Fonts You Want to appear in LibreOffice Writer.
Kill the LibreOffice process so it is not running.
Rebuild your font cache:
fc-cache -f -v ~/.local/share/fonts

Launch Writer and set View > User Interface > Language Settings > Languages to Western
Then check if it is only showing too many fonts.


On Font Manager:

apt search font-manager                                                                        ─╯
