Can Superset v5 enable system-wide dark/light theme + Roboto font purely via superset_config.py (no frontend rebuild)?

[user1500177]

I am currently running Superset version 5.

I cannot rebuild the frontend or change compiled source code. I want to:

1. Change the font family to Roboto — is this possible?
2. Implement dark and light themes for the system? (I saw this is supported in Superset version 6 — but I am on version 5. Is it possible there?)

Are these best supported only in Superset 6.0.0? I do not prefer using workarounds or changing the source code. Can these be configured via superset_config.py in version 5?

Superset v5 does not support changing the font family to Roboto or enabling system-wide dark/light theme switching via superset_config.py alone, without rebuilding the frontend or modifying source code. These features—runtime custom font loading (like Roboto) and config-driven theming (including dark mode)—were introduced after v5 and are officially supported starting in Superset 6.0.0 and above. In v6+, you can configure these directly in superset_config.py without frontend rebuilds or workarounds (details, docs).

To reply, just mention @dosu.
