Use ReActor or Roop extensions for A1111

If you have some Buzz to spare, you can submit a bounty and have someone make a LoRA model for you. But you need to be more specific and clear what exactly do you want the model to generate.

Not sure if you have more images of the person (and the person's permission), but if you do, there are a lot of tutorials on this site for making your own LoRA to generate the person's face. One by me is here: https://civitai.com/articles/391/tutorial-dreambooth-lora-training-using-kohyass

9-15 pictures from the same person by multipule view, name it in caption,

make LORA with 500 Buzz, choose 【Realistic】or 【SDXL】as base model.

wait and the you will have an own LORA, then use it when generate the images.

Reamber! Obey The LAW as you are training a real person.
