Fine tuning Flux LoRA without Dreambooth

[LearningLeopard]

Hi,
Thanks for such awesome repo and code scripts.
I am a beginner in fine-tuning models like flux so please bear with me if some doubts are too vague.
I was wondering if I do not give dreambooth-subject dataset in the dataset configuration, will that lead to model not tuning.
Basically my question is that can I finetune the Flux model with LoRA without dreambooth configuration?
The reason is that I do not have any style transfer task here. I am looking ways to improve the model in aligning with some specific prompts.

Thanks in advance for your time!
