I cant answer for sure, but in case of ROM USB probably there is not possible. Maybe with large volumes espressif can burn customized ROM, who knows.
You can also use tinyUSB and in that case check this:

I can answer for sure. The ROM driver descriptors indeed are not modifiable. Please use TinyUSB if you want to have a custom descriptor.
