Is there a way to use the Bluetooth advertising extended mode in micropython?
I don't have an answer for you, other than to observe that MicroPython, including the port to rp2/pico boards, is developed and maintained by an organisation of that name, not by Raspberry Pi.
You might get knowledgeable input by asking your question in a dedicated MicroPython environment?

This might be related, but does not look encouraging...
