How can set up my iPhone so that it is automatically in silent mode when I'm at the office?

Is there a way to configure an iPhone such that it is automatically in silent mode at a particular physical location? The obvious approach is to use Work focus mode, which I can easily configure to automatically activate when I am at my workplace. But I can't figure out how to configure a focus mode so that it silences the ringer / notification sounds, _without completely suppressing the notifications themselves_. I only want it to do exactly what it would do if I manually switch the physical switch to silent mode: that is, vibrate and show notifications and notification dots, but not make any sound.
