Chrome new grid layout for tabs

I've tried with *chrome://flags/#* disabling *tab-grid-layout* reloading several times the browser, but no change works. I've read a lot of articles on the web, some of them indicate this procedure, others to disable also flags like *tab-groups*, and so on, but currently nothing seems to work. (In fact, *tab-groups*, on the last Chrome realise, isn't available.) Any solution?
