怎样在操作系统(debian)设置字体配置文件，实现英文DejaVuSansMono，中文NotoSansCJKSC显示？

Question

这个"增"字在我的操作系统(debian)中（不是网页中）显示文件夹名。

操作系统信息

uname -a
Linux debian 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64 GNU/Linux

我系统中的字体：

fc-list |grep vlgothic
/usr/share/fonts/truetype/vlgothic/VL-PGothic-Regular.ttf: VL PGothic,VL Pゴシック:style=regular
/usr/share/fonts/truetype/vlgothic/VL-Gothic-Regular.ttf: VL Gothic,VL ゴシック:style=regular

既然它是有版权的商务字体，那我就删除它。

sudo rm -rf /usr/share/fonts/truetype/vlgothic

重新启动系统，再次显示这个字。

请问，这次又是什么字体呢？它不是上次的字体，也不是noto sans cjk sc.

我希望设置字体配置文件后，英文用 DejaVu Sans Mono显示，中文用 Noto Sans CJK SC 显示。配置文件/etc/fonts/fonts.conf。

重启电脑，设置目标不能实现。
