Macros on Cardio/Conditioning Days

I’m starting to do my conditioning in the morning about 3 times a week while lifting 4 times a week. I’ve always been unsure about how many carbs/fat I should take in on the cardio days. I usually take in 200+ grams of protein and 200+ grams of carbs and around 70 grams of fat.
I know I should probably cut my carbs to around 100g or so, but does that mean I up the fat?
I’d appreciate some insight and general logic.
