I personally don't think so but it depends on how late you decide to get there as well as the amount of time you spend in the World Showcase pavillions. If you're a 1 loop of the showcase making only short stops and eating a meal there you're fine, but if you want to spend significant time in the World Showcase you shouldn't get to the park too late. Although there are only 3 big rides the shows and Spaceship Earth can be time eaters due to their length, and like I said looking around the showcase just evaporates your day if you're not careful.
I would suggest showing up before lunch and getting one of Soarin or Test Track out of the way and just make sure you do the other at the end of the night. I've found with social distancing Frozen doesn't get too long since there isn't a ton of space inside, so the line looks a lot longer than it really is. I don't think doing Frozen around the middle of the day will be too bad. So my strategy would be Soarin when you show up and do Livin with the Land while you're in there -> Do the rest of Future World besides Test Track that you're interested in (so Nemo/The Seas, Figment, maybe Spaceship Earth if the line isn't too crazy since it gets to a walk on in the evening, Mission Space if you're into that) -> World Showcase for as long as you want/need -> with about an hour left in the day head to Spaceship Earth, it should be a walk on. -> That should leave about a half hour or so to get in line for Test Track at the end of the night, I did this in December and waited about 20 minutes on a posted 45 minute wait.
