Can you spend 23hr fasting, e.g. just drink water between the evening meal one day and the next day? This may brink down the BG levels. (Not to be done if someone is on drugs/insulin without thinking about the drugs first!)
Some people find that 5:2 works well on top of their low carb, e.g fast for two non-consecutive days.
And as everyone else is saying see your GP and consider going on Metformin, if you GP thinks you need something else as well as Metformin talk to him/her about Forxiga as unlike most drugs (apart form Metformin) used for Type2 it does not make insulin resistance worse.
Assuming you have already got your carbs down to below 40g a day, reducing protein and hence increasing fat (olives, oily fish etc) may also work.
