To eat low carb vs keto will mean doing the same but at higher levels. Eg. instead of sticking at about 30g carbs daily you could aim for 100g. You would still need to measure what you are eating to keep within the target.
Alternatively, you could aim for a level of carbs per meal which causes only a modest rise in post prandial bg. You would need to count carbs and monitor before and 2 hrs after eating.
Either way a certain amount of food logging, carb counting and blood testing will be involved I'm afraid, but at least you will get a greater choice of food (hooray!)
