I have a basement that stays cool and I will store a jug of DEF there. If your garage is 100 degrees you should buy your DEF as you need it.
The vehicle stays hot in Phoenix - day after day with only a slight cooling at night.
Thousands of vehicles and it doesn't seem to be a problem for them.
And that includes stations where DEF is sold and stored at outdoor kiosks.
I wouldn't worry about temperature too much.
