I am glad you like it. (Not perfect but I enjoy it very much.)
Do you mean Waydroid's icons?
You can find icons in ~/.local/share/applications. If you add the following into them:
This will hide that icon in Sailfish.
Instead of hiding, I've put all of those apps (icons) into one folder in Sailfish, so they are not in the way but can access them if I need.

(Try the following: let Waydroid start fully, then close the screen with the usual Sailfish gesture. Then click on an android app icon. Not the best app integration but it does work.)
