Short answer is yes, @chad.andrews and @WMarcolin worked on doing this, but also removed the thermostat mode selection, not sure if you still need that or not...
If you want to just mess with the listing in the pop-up you can use this CSS, but I expect you want to remove the Fan Mode option from the tile altogether.
If you are going to play around with the driver, you may want to look at the supported fan modes method, I think it works they way I expect, where you can pass in a list. You could add a command to the Device page to set them how you want, or just add the call into the code to set it through values you include in the driver code.
