The 1.6L GDI engine does too if you read the RHD manual.
And to add, my New Zealand 2017 2.0 GDI Tucson allows a 50 grade per the user manual! View attachment 69373
Point *1 is interesting if you read between the lines. Hopefully there are no compromises with getting better fuel economy. Interesting in this case the 1.6T doesn't allow a 20. Cujet, yes good point you made Re chains. It's quite possible that the heavier oil will have benefits in that area.

There of course is a compromise for better fuel economy.

The Toyota 2020 1GR-FE engine sold in Europe has an oil viscosity specification ranging from 5W-30 to 20W-50, which is a difference of 15 points in the first value and 20 points in the second. In the USA, Toyota recommends 0W-20 for my 1GR-FE engine. I think it will run just fine with 5W-30.
Absolutely Doug. Go for it.
