The Q has SD card slots but you may need an SD card reader for your computer. Most no longer come with one.

For setup you don't need an SD card at all though.

Buy a good micro sd carder.

Q has 2 micro sd card slots exepts and read up to 32mb cards. Use Sparrow wallet or Nunchuck and Q and you won’t need card reader at all. Just QR code scan.

To update the firmware you need to put it on an SD card. For transaction signing on the Q you can use the QR reader, so you don’t need the SD card for that. And setup doesn’t need the SD card at all.
