Hi Jonathan,

Thank you for the suggestions in your recent email. Following your 
advice, I discussed these configurations in detail with engineers from 
the HX9023S supplier. Based on their feedback, these settings are not 
intended to be exposed to end-users. Typically, these configurations are 
adjusted during the DVT phase of the end product by the supplier to 
optimize performance, after which they are finalized and not meant to be 
modified dynamically at the user level.

Given this approach, it seems more appropriate to provide these settings 
as part of a firmware file, allowing the configuration to be kept 
internal and managed without user-level access. If this approach aligns 
with your thoughts, I can prepare and submit a new patch focused on 
firmware parsing and handling for these configurations.

Thank you again for your valuable guidance, and I look forward to your 
feedback.

Best regards,
Yasin Lee
