Can anybody help me with a customized firehose loader file for sm8475, Oppo Find N2 phone

I'm looking for someone to help me get a customized firehose loader file for my Oppo Find N2 phone. Chipset is Qualcomm SM8475 Snapdragon 8+ Gen 1 (4nm). This is for personal use and I understand the technical jargon associated with the project so I don't need any help understanding the documentation. I'm looking for a completely customized solution and don't need help with formatting the firehose file.
