I don't think so


In class _PollLikeSelector ,here's register method

def register(self, fileobj, events, data=None):
        key = super().register(fileobj, events, data)
        poller_events = 0
        if events & EVENT_READ:
            poller_events |= self._EVENT_READ
        if events & EVENT_WRITE:
            poller_events |= self._EVENT_WRITE

this code filter the event that people push in it. It only supports select.EPOLLIN and select.EPOLLOUT
