Sorry, but I don't think this is possible with the way my tool works.

The features you want to add are selected by compiler switches before the firmware is compiled. For example, there is a switch called _HDMI_SUPPORT. If it is enabled, code for HDMI support is compiled into the firmware. If it is not enabled, the code will not be included in the firmware.

My tool modifies only few bytes in the binary firmware. It doesn't add new code or removes code. For the features you want to add, we would have to add new code into the binary firmware. This is barely possible. It would require us to update all memory addresses in all memory instructions. We can't do this with a binary firmware.

A better approch for you would be to compile the firmware for your board yourself. You can find the firmware source code on the Internet. There is also a project to write a custom firmware here. But I don't know if they are still actively working on it.
