well there’s a number of drs and dieticians that are offering and perhaps even recommending low carb and the guidelines I’ve found so far do not seem to prohibit advocating low carb. I’ve met a few of them (some tentatively) supporting it as a valid option.
There is a fair amount of evidence based information on the phc website supporting the use of low carb lifestyles. Whilst I accept they may not be seen by GP’s that is in fact one of their goals - to get the evidence seen by the drs/nurses and provide some of that dietary structure that appears to be missing from their guidance to patients. Many T2 patients never see a hospital dietician and rely on their gp and practice nurses.
I personally believe drs refusing to support a low carb dietary option do not want to, rather than are unable to do so within regulations. I’d like to see clearer guidelines and regs more inclusive of lchf but until then the current ones can still be utilised. If I am wrong (it can happen) I’d be interested to see the evidence.
My GP is responsible for my care as my Named Responder under the individual care scheme. He reports to the Senior Clinician in the CCG that controls funding and admin for the practice. They determine daily priorities and protocols, and determine medication and support strategies at the local level (postcode lottery) So for example they decide which bgl meter I can use, and how many strips if any I am allowed a month. It is bread and butter stuff, but they also look after the District Nurses, and the local Care providers. They also look after the support network such as podiatry, opthamology etc, and replace the older Trust based network. They are only Primary Care, so do not control hospitals.
The Nutritionists are responsible to the health system by another pathway too, and are regulated seperately. GP's do not have nutrition expertise, and are expected to subcontract out to the local support group who are normally attached and run from the District Hospital Trust.
Here is a typical nutritional datasheet currently distributed to all local practices in an area controlled by this CCG.

These practies are expeted to support this. It is not for the GP to question this advice since it is deep rooted in government initiatives, so although it maynot be a legal binding, it is a professionsl binding none the less. Since the GP is not a apecialist he must bow to those holding that knowledge and that is determined higher up than tha locaal level.
The dietitians are regulated as shown here

Until these people accept LC diets as being viable, then things will not change in any hurry. This is where regulation comes from, not the local GP surgery. So lets stop dissing the doctors and nurses. It is not their fault that things are pearshaped. As I said initially in my first response here, my GP is supportive of my diet, but cannot recommend it to anyone fur to professional etiquette and possibly contractually too. My GP and I have a very good relationship and he allows me to control my medication as I request. He does not bully or browbeat me so he is indeed following NG28 properly.
At the end of the day most of us here have a right to refuse to accept a GPs advice and eat whatever we want to. They do not have control over what we eat unless we are in dependant care eg nursing home or other institution. They are obliged to support your medical condition, and if going low carb works for you, and your bgl drops, your BP drops, or your weight falls away then they must alter your medication to suit the new you. This is what I did, essentially railroaded my GP to recognise that I was back in control, so cur the meds, please. He was so surprised at my first HbA1c following starting my LC journey that he gave in without a wimper and has been with me since.
So to return to the OP. You do not need the GP to agree to your diet. Just do the research yourself, invest in a test kit and start keeping a food log and plot your progress as you Eat to Meter. Then go back when you have something to discuss. If it works, then it will show up in the next review. If not, then try something else. The main thing is to gain knowledge about how your body reacts to food, and this will give you the amunition to fight for your corner. Such knowledge is invaluable, and the more research you can do the better prepared you will be to take back control for yourself.
