Using third party ad-blocker plug-in (like Ublock Origin, etc.) is the only option at this time which works.

Any ad-blocker which supports blocking selected page element would work. In Ublock Origin function called "Element zapper mode" and it does exactly that, once you zap the element it does not reappear.

It is very easy to do and after few days of use did not pose any side effects.

Needless to say that this is ridiculous to be the official solution from the QBO support team (as I was told today) and a sign of neglected software product - happens almost always with dominant market position...
