Wish we could but, unfortunately, it is not possible to disable elements when someone places a row there. However, I think that most of Impeka elements are supported by the tabs element. If you check the Elementor tabs, you will see that you can add only text. In general, you should never overdone by placing elements that require scripts.
I have also checked the Gallery element and I see only the isotope load effect which is pretty normal. If this is what you mean, there is nothing to be fixed as we have to trigger the isotope after the click on the tab element. Otherwise, we will have a broken layout. I guess that you don’t see this if you place the gallery in the first tab.
