Dry shaving is unlikely to produce comfortable close shaves.
Blades used for shaving need to be honed to a higher standard than kitchen knives and should not be used for any other purpose, which would dull the blade.
As it should be a dedicated blade for the shave it makes sense to buy a straight razor, the shape of which has evolved over 200 years and that is (ergonomically) optimized for the purpose.
There is a reason for the existence of shaving soaps/creams, but if you do not want to use either, you could try facial soap (in the absence of an alternative, I have shaved with Valobra facial soap before) or - after thoroughly softening your face with warm water - a light (massage/skin/shaving) oil applied on a dry face.
All these things are possible, but the all will diminish the quality of the shave.
Lastly, shaving requires skills that need to be learned and practiced.
For most straight shavers it took up to 100 shaves to come close to their final shaving performance.
With what you set out to do, you may be able to get an adequate shave with sufficient practice, even if the shave - due to the limitations imposed by you - will fall sort of what most of us here are attempting to achieve.
