How do I hide track data in the automation lanes?

Does anyone know how I can hide the data (greyed out notes) in the automation lanes?
I’m using Cubase Artist 9.5
In Cubase Artist 8 I just closed and re-opened the automation lanes and the notes hid themselves, but I can’t do it with this version.
Elsewhere in the forum it says this behaviour can be controlled in the automation panel, but I don’t think this is available in Artist.
