Can you launch a browser dashboard with the left sidebar collapsed?

To save space, I would like the ability to launch a dashboard with the left sidebar already collapsed without having to click the left hamburger icon – ideally on a per dashboard basis (e.g., bypassing a parameter notionally like ?collapsed=true) or as a system or user-wide default.

Is this possible in a simple way?

Thanks!

Open your Home Assistant instance and show your Home Assistant user's profile.

That’s great but what I really want is minimize the left sidebar, not hide it
