There are wall bracing methods that don't use structural sheathing, and were used by a lot of designers and builders for years. When OSB was cheap and plentiful, it became the preferred method in a lot of regions. Now, it feels like we may need to re-learn how to do it without the OSB. But no matter what method you choose, and whether it's prescriptive or engineered, following the details is critical, from the foundation to the roof.
Start with IRC 106.1.3, where they can be required to show you where the bracing is and what methods they will be using. Then it's just a matter of deciphering the requirements...good luck. CS-WSP would require a 6"/12" pattern, stud spacing is dependent on other factors, such as fastener size, stories, what story etc.
IMHO, the code jumped the shark with wall bracing, too many variables and options. I haven't seen a non-engineered design in years, and I don't want to.
