Unfortunately no. Not even with the 3rd party modifications. Though there are some full GUI linux installs iirc.
It's a common question in the community Discord, and the official patches have been accelerating and implementing a lot of long-asked-for features (e.g. pinch to zoom), but nobody really knows what's on their roadmap. So hard to say if it'll ever get side-by-side.
Hopefully they add open sourcing the whole stack to their roadmap. That'd be the best thing they can do imo. I'm so eager for a device like this that I can 100% get behind.
