No, for blinds you need a special module that can control the blind with two contacts. these contacts are then to be connected instead of the conventional blind control buttons.
Not directly. But it would be possible somehow. e.g: Button / switch connected to the hue wall switch > reports button press to Hue Bridge via Zigbee > Hue Bridge integrated e.g. in Home Assistant > Home Assistant receives the signal via LAN/WLAN from Bridge > Home Assistant sends command to close/open blinds e.g. to a Shelly 2.5.
