I think that’s right to try by just ramping up the quality carb intake before/after workouts and seeing if that has an effect. The Whole30 doesn’t have to be a low carb plan (although lots of people end up that way by cutting out garbage carbs) and I do think you can balance training and quality nutrition if you’re thoughtful about it, which to me means keeping good quality carbs in every meal to support a modest training load.
