How to rebuild Qwiic Micro board arduino bootloader

Dear Sir,

As title, how to modify bootloader? I want to disable MSC(mass storage) and SPI port.

The UF2 bootloaders are maintained by Microsoft, your best bet would be looking at the GitHub repo. https://github.com/sparkfun/Arduino_Boa … ootloaders
