Proper prompts to disable window lighting from my image

[Trylz]

I am adding stable-diffusion to my software. I want to disable some window lighting that the kernel added to my scene,
Here the source image:

Here the output of stable-diffusion :

I want to disable/remove theses windows

Here the cli i am trying but it does not work as expected
sd-cli.exe --backend cpu --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q4_K_XL.gguf --vae flux2.full_encoder_small_decoder.safetensors -p "turn the image into a high quality photograph." -n "Windows" -r BathroomSRC.png -o output_photo.png --cfg-scale 1 --steps 4 --offload-to-cpu --steps 4 --fa

This one is trickier, even with negative prompt it really wants to put windows there.

My best attempt:

sd-cli.exe --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q46_K.gguf --tae taef2.safetensors -p "turn the image into a high quality photograph, studio lighting." -r BathroomSRC.png -o output_photo.png --cfg-scale 1 --steps 4 --offload-to-cpu --fa

Changing seed might also be a way to give the opportunity to the model to interpret the image differently.

with different seed and cfg:

sd-cli.exe --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q46_K.gguf --tae taef2.safetensors -p "turn the image into a high quality photograph." -n "Windows" -r BathroomSRC.png -o output_photo.png --cfg-scale 2 --steps 4 --offload-to-cpu --seed 67 --fa
