Can you use an Android phone as an NFC-USB keyboard?

Some NFC readers emulate a USB keyboard, so that when you read a label, the "keyed" serial number. The serial number is usually fixed and can not be written by any normal means.

Android supports NFC tag emulation. Is it possible for an Android device to "write" an arbitrary string using an NFC reader that emulates a USB keyboard?

Note that the string must be configurable, not a fixed ID. Also, additional software may not be required on the computer side, since it has to work before loading Windows (for example, in the BIOS, like a normal USB keyboard).

I am aware of this question, but all solutions require software from the PC side to function.
