I guess not. I still can't find where to do that. It's certainly hidden from my eyes. Main menu Edit?
Yes, but you have to make sure the track itself is selected first, then it's Edit > Delete Special > Track/Bus Automation
This will of course delete ALL of the automation on the track, which might not be what you want.
You can also toggle Automation Lanes on/off then like Kev999 says, you can then right click on the envelope itself in the automation lane to delete it, or, in track view without the lanes open, you need to set the Track Edit Filter to Automation > (envelope you want to work with).
All envelopes will show as "ghosted" with the Edit Filter set to Clips
