I mean for example, at first, I report a top-level collection which is
a keyboard.
Later on, can the driver report a top-level collection which is a
mouse? So that the HID keybard
disappears and a new HID mouse appears in the system.

Cheers.

No, you cannot change the hid descriptor after it is initially queried. If you want functions to change state, just stop sending data through them. The only way to have them come and go would be to install multiple instances of your miniport and each instance has a differemt hid descriptor
