How to remove "Save as Tile"/ Share icon from standard Fiori Applications?

Hi Experts,

I need to remove "Save as Tile" option from all the views from my standard Fiori application "My Timesheet".

Please guide me how can I achieve it.

Because with this option available, when users click on "Save as Tile", a Weekly Tile is created in the launchpad which behaves inappropriately.. i.e.

Even after the whole week is approved, it still allows users to enter new entries.

Customisations do not take effect in such a tile. Please let me know how to disable/remove it.

Regards,

Lipsa
