A motorized shade is possible but very expensive and you would have to run wire because they take 35V and do not come as battery operated. They are also tension so the casette would be at the bottom and you would have cables running up to the top of the window.
Another solution would be fixed shades by Insolroll - but you wouldn't be able to open and close it; would be fixed.
Personally i would go for the fixed shade option over tinting.
The one time something looks increasingly innocuous the more you slow it down.
