Applying for Provisional Driving licence and passing test but not buying a car?

Hi, I am thinking to apply for my Provisional Driving licence and then go through the process to pass the test to get my full driving licence by passing the road test.

I do however not intend to buy or lease a vehicle, and I do not intend to drive.
It is simply something that I want to do as a first step, and then possibly look at driving. Also this way I don't feel rushed to get the licence quickly.

Would this likely affect my PIP since I get both at the enhanced rate, and would it likely affect Mobility Activity 1: Planning and following journeys?

Also, I am wondering, as my conditions are OCD predominantly, as well as sciatica and depression (with suicidal ideation) for the most part, which I do not believe make me a danger to road users if I have a licence to drive (since my conditions either would make me not set out on a journey in the car/at all in the first place or would make me safely pull to the side of the road, or possibly backtrack on where I have driven wasting petrol due to OCD), but could this potentially be an issue with the DVLA?

I read the conditions and driving part and I am not sure if I need to notify the DVLA if I feel that my conditions are not going to affect my ability to drive safely (sorry if that question is a bit outside of the benefits help aim of this forum, but wondering if anyone has knowledge or experience regarding this?).

First thing that came to mind was that not driving after getting the licence would effectively render it a non-issue since 0 days of driving is clearly less than 50% of the days of the required period being assessed, and thus shouldn't theoretically affect how they assess me.
Surely having a licence and passing the test is done as a once time thing, and PIP should not really take that into account if I do not feel that I would be able to actually drive more than half of the time anyway, or would by passing the driving test and being licenced would they assume that if I am licenced to drive anytime I want (which is what a licence is after all), then would the DWP consider the licence itself evidence that I am capable of driving more than 50% of the time regardless of how I would actually feel up to doing this? After all there is no requirement of a licence holder to drive on more than 50% of days if they do not feel up to it for reasons other than being deemed able to safely operate a motor vehicle, which is really all they test for when going for a licence right?

Sorry if my last paragraph is a but confusing, but I am trying to view this in 2 possible ways that it could be interpreted (actually being granted a driving licence) and my view that it should be taken that if one does not feel up to driving on more than 50% of days for reasons which would not seem to medically cause a licence to be revoked by the DVLA, if that makes sense.
An example I am thinking of is that illustrates this point I am making is that being too anxious to drive on most days or only driving at quiet times would likely not be seen as a danger to road users, and this not be a cause for the DVLA to revoke the licence. Hopefully any answers to this can help others regarding the driving thing and simply possessing a driving licence, which is why I am wondering about how the DWP interpret the core sole issue of holding a drivers licence itself regardless of driving or owning a vehicle.
