For the similar nanovna, each different screen size requires different firmware modifications - they have done the 2.8", 4", and recently adapted a 7" display to the newer litevna.? So it is highly unlikely that there is any plug-n-play larger screen for the tinySA.?
Just had the thought that maybe if the display uses spi, then something designed for an arduino or raspberry pi could be used.
?I may be way off in my thinking there, but it certainly seems feasible.
