In Safari 14 on macOS Big Sur 11.2.1, How can I mute the current tab in Safari when it isn't playing audio right now?

You'll have to create your own keyboard shortcut that toggles the menu bar commands under Window (otherwise you'll see that there are no keyboard shortcuts listed there).
Keyboard Settings - Shortcuts - App Shortcuts - "+" - Safari, Mute This Tab, (insert desired shortcut)
Repeat for "Mute Other Tab" and "Mute Other Tabs" (multiple "other" tabs open).
NOTE: Play/Pause button works for YouTube (pauses last video interacted played/paused), possibly other sites as well.
Right clicking the sound icon in the address bar will give you this functionality too, but requires the mouse.
If this happens in Safari, the tab for a site that is playing audio will have a small speaker icon on it. See the image below which shows 3 tabs in the top of my Safari window. Clicking on the speaker icon stops it from playing. See the middle tab in the image.

I don't think you can.
Even if you add a key command, it simply doesn't respond & stays greyed-out unless there is actually audio playing. It doesn't even highlight if video is playing, if it has no sound.
