You can't.
Book what you need and be happy with anything else.
I've had better luck with suite upgrades at Hampton Inns and Hilton Garden Inns (which are excluded from the upgrade benefit T&Cs) than at larger resort or full-service properties. There are so many different types of rooms that you may book a 1K standard room and get upgraded to a 1K standard room on a higher floor.
In my experience, true upgrades to suites happen rarely, but are usually at properties where I've stayed multiple times in the past.
