How to display a custom message on the home screen

Question

Hi all
Is it possible to display a custom message on the home screen on Odoo online, without having to install any additional modules? The goal is to be able to show custom messages to users, like planned maintenance and stuff like that.
I'm thinking about something similar to the expiration messages in a test database, that show above the apps, or something like the neutralized databased banner.
Thanks!

I am sure you can configure different initial dashboards and assign them to the different g
