I'd like for this not to show the $11.64. Seems like it's not possible. Can anyone confirm?
For the Radial Gauge card there are not any Hover text settings. Confirming that there does not appear to be any way to change or hide this on the Radial Gauge chart type.
Comparative fill gauge has these options, Radial does not. I would suggest posting this in the Idea Exchange, tag me and I'll upvote it.
