Maybe xrandr could help (if you use X server)?

Something like just

$ xrandr

to learn about your default output name and its properties, and then

$ xrandr --output DP-1 --dpi 1000

Replace DP-1 and 1000 with what you need.

The downside of this approach is affecting other apps.

Apropos, it works with gtk2 for fonts, though PCB icons are not scaled.
Well, here shortcuts may help.  OTOH, it doesn't work at all with gtk3
apps on my system, I tried some, though it's not your case, I believe.
